Procedure

1. SUBTASK 70-34-01-340-001 Preparation Procedures

   1. NOTE

      It is permitted to use TASK 70-34-18-380-501 as an alternative to Step.

      Condition of the part.

      1. All chemical or metallurgical procedures that can cause damage to the coating must be completed before the coating is a applied, unless sufficient protection is first applied to the coating. When necessary, special instructions are given in the Engine Manual.

      2. All parts to be sprayed must be free from corrosion scale and contamination.

      3. Degrease the parts using one of the following methods:

         1. The same degreasing method used in the usual cleaning of parts in the engine overhaul can be used for parts that are to be plasma coated. Ensure that the components are fully dried after degreasing.

         2. Refer to SPM TASK 70-11-03-300-503. Vapor degrease then allow the parts to cool.

         3. If small areas are to be coated locally degrease. Refer to SPM TASK 70-11-26-300-503.

   2. Surface preparation.

      1. Do one of the procedures in the subsequent list:

         1. SPM TASK 70-34-18-380-501

            1. It is permitted to use SPM TASK 70-34-18-380-501 as an alternative to the specified surface preparation procedure in the applicable repair task, including source demonstration repairs, if the resulting thermal spray coating agrees with all specified quality requirements.

      2. Abrasive blast the part.

         NOTE

         CoMat 02-001 ADHESIVE TAPE (MASKING) or CoMat 02-006 ADHESIVE TAPE ALUMINIUM FOIL or CoMat 02-198 ADHESIVE TAPE (MASKING METAL SPRAY) or mechanical masks permits blasting and spray coating to be done in one operation, which makes it not necessary to do the masking removal step at the end of this abrasive blast procedure.

         1. Apply CoMat 02-001 ADHESIVE TAPE (MASKING) or CoMat 02-006 ADHESIVE TAPE ALUMINIUM FOIL or CoMat 02-198 ADHESIVE TAPE (MASKING METAL SPRAY) or mechanical masks. Apply protection to holes and passage ways with blanks or plugs.

         2. 

            CAUTION

            REFER TO SPM TASK 70-12-01-120-501 FOR PRECAUTIONS NECESSARY WHEN DRY ABRASIVE BLASTING MAGNESIUM ALLOYS.

            Dry abrasive blast the surface to be prepared with CoMat 05-001 ABRASIVE MEDIUM, ALUMINIUM OXIDE, 20/30 GRADE, CoMat 05-015 ABRASIVE MEDIUM, ALUMINUM OXIDE or CoMat 05-192 ALUMINUM OXIDE GRIT. When thin parts are to be prepared, use CoMat 05-015 ABRASIVE MEDIUM, ALUMINUM OXIDE or CoMat 05-192 ALUMINUM OXIDE GRIT. Finer grades of abrasive media may be used provided that an acceptable bond strength can be achieved. Blast the surface for a sufficient length of time to get a constant, matt finish. Use an air pressure of 20 to 40 psi (138 to 276 kPa) when pressure pot abrasive blast equipment is used, and 70 to 80 psi (483 to 552 kPa) with vacuum pick-up abrasive blast equipment.

         3. Remove remaining dust by a dry air blast.

            NOTE

            Remove the masking carefully, the blasted surface must stay clean and untouched. If contamination occurs, remove the grease, then mask and blast again.

         4. Remove the masking.

2. SUBTASK 70-34-01-340-002 Spraying Procedures

   1. Bond coatings.

      1. For some conditions it will be necessary to apply a bond coating, between the base material and the top coating, because of the conditions that follow.

         1. To get a better bonded system.

         2. To limit the thickness of high stress top coatings.

         3. To get a ductile initial layer.

         4. To get oxidation resistance.

      2. Bond coatings must only be used when specified in the Engine Manual or recommended by International Aero Engines AG.

      3. Materials usually used for bond coating are as follows:

         1. Bond coat CoMat 03-038 METAL SPRAYING POWDER NICKEL ALUMINIUM (95/5) or CoMat 03-036 METAL SPRAYING WIRE, Ni,Al or CoMat 03-248 METAL SPRAY POWDER, have a top coat examples of abradable linings, Cu/Ni/In, Wc/Co for where general application bond coats are necessary.

         2. Bond coat CoMat 03-262 METAL SPRAY POWDER or CoMat 03-265 NICKEL CHROMIUM ALUMINIUMPOWDER, have a top coat examples of ceramic coatings, magnesium zirconate or yttria stabilized zirconia.

      4. Apply the bond coat to the data given for the applicable powder as referred by CoMat numbers in Figure and Figure and Figure and Figure and Figure and Figure and Figure and Figure.

      5. The thickness of the bond coating, unless used to limit the thickness of the top coating, must be sufficient to give a continuous coating of between 0.003 to 0.005 in. (0.07 to 0.13 mm) thick, unless differently specified in the Engine Manual.

         NOTE

         Because a blasted surface can easily become dirty again, it must be sprayed as quickly as possible after it is blasted. If the part is not sprayed in two hours after it is blasted all of the preparation work must be done again.

         The spraying procedure must be, when possible, be continuous. Short stops, to measure the applied coat thickness, can be accepted, but they must be kept to a minimum, to prevent 'layering'.

         Where it can be done, the spraying operation must be controlled automatically for the spray angle and distance and the motion between the gun and the work piece. For example, install the gun so as to get vertical or horizontal mechanical traverse and mechanically turn the work piece.

         The direction of spray must be kept as near as possible at right-angles to the surface being sprayed. The angle must not be less than 50 degrees. Work piece and coating temperatures must be kept below 338 deg F (170 deg C). This is specially important when spraying materials give an exothermic effect such as CoMat 03-037 METAL SPRAYING POWDER,Ni Al or CoMat 03-038 METAL SPRAYING POWDER NICKEL ALUMINIUM (95/5). Facilities must be supplied to direct a clean, dry air flow over the component in such a way that the flow of sprayed material is not impeded, or a different spraying/cooling operation may be used. Remove all 'bloom' or 'smoke' with a clean, dry, air blast before more spraying.

   2. Spraying operation.

      1. NOTE

         The spraying data given are those approved by International Aero Engines for the equipment given.

         Get the necessary data for the material to be sprayed from the table referring to the SUBTASK and CoMat numbers given in the Engine Manual.

      2. Spray the test pieces (refer to General section, Test Pieces) to check the coating bond, hardness and the satisfactory condition as necessary.

         NOTE

         Parts must not be sprayed until satisfactory tests have been completed.

         The condition of the equipment is very important, if the adjustments found are to be used again. This is specially important for plasma equipment, where a high standard of inspection and maintenance is necessary. (Refer to Equipment Maintenance section.)

      3. Protect the areas which are not to be sprayed by the use of an applicable masking tape, masking compound or mechanical mask. Plugs are recommended to protect holes or passages.

      4. Install the part for spraying.

      5. Most components will require a preheat, and the preheat control must be specified in a local work instruction. Generally several passes of the flame (without powder) over the component will be satisfactory. If no preheat temperature is specified, use a preheat temperature that does not cause discoloration, oxidation, distortion, or other conditions that can have a bad effect on the coating or base metal; and is not more than 302 deg F (150 deg C).

      6. Spray the part, when it is warm, to the necessary thickness.

      7. Apply the bond coating if specified.

      8. Apply the top coating immediately after the bond coating is applied.

      9. To prevent coating/base material corrosion problems on magnesium alloy parts, sprayed coatings must be soaked to seal the coating and prevent entrance of water, immediately the part is cooled sufficiently to handle after spraying. CoMat 08-067 THREADLOCKING MATERIAL must be applied to the coating by brush.

         CoMat 08-067 THREADLOCKING MATERIAL must be applied again after all post spraying machining operation.

      10. Where necessary, after spraying, temporarily protect the areas which have not been sprayed on the work piece as specified in the SPM TASK 70-38-05-380-501.

   3. Examine the sprayed parts.

      1. Before finishing, examine the coating for dimensions and a smooth surface, to make sure it has not peeled, lifted, cracked or chipped.

         NOTE

         The inspection of the ground coatings is very important to find possible damage to the grinding wheel.

      2. After finishing, visually examine the coating by the use of a magnification of up to x7 where necessary. A satisfactory coating has a matt finish, in which the machining marks can easily be seen. There must be no color change, and the coating must not be cracked, spalled or polished. Less important chips, at the edge of the coating and not related to the condition of the bond, can be accepted for some uses. When necessary, the standard that can be accepted are given in the Engine Manual.

      3. Removal of defective coatings.

         Remove all defecting coatings by one of the procedures that follow, unless specified differently in the Engine Manual.

         1. Remove the coating by machining.

         2. Remove most of the coating by machining followed by the chemical removal of the remaining material by the procedure given in the SPM TASK 70-33-59-300-503.

         3. Remove the coating chemically as given in the SPM TASK 70-33-59-300-503.

      4. Temporary protection.

         1. Where necessary, apply temporary protection, between spraying and machining or after machining, as given in the SPM TASK 70-38-05-380-501.

3. SUBTASK 70-34-01-340-003 Finishing Procedures

   1. The quality of a flame sprayed coating is controlled by the finishing procedures used. The instructions that follow will help in the selection of the correct procedure.

   2. Three basic procedures are usually applied.

      1. Turning.

      2. Grinding.

      3. Buffing.

   3. If no special procedure is given in the Engine Manual, refer to Figure which gives the recommended procedure for each type of coating.

      1. Turning.

         1. Some coatings can be turned (Refer to Figure), when a tipped tool must be used.

      2. Grinding.

         1. Flame sprayed coatings are usually ground with aluminium oxide or silicon carbide wheels. For some operations (For example, large diameters on flexible components, or when tungsten carbide or chromium carbide coatings are applied) wheels that contain diamond particles are necessary.

         2. The wheel grit sizes are different, for each surface finish and procedures used, but these are the usual recommended sizes.

            1. Surface grinding use Diamond 180 to 230 or Silicon carbide 46 to 80 or Aluminum oxide 46 to 60.

            2. Cylindrial grinding use Diamond 180 to 230 or Silicon carbide 60 to 80 or Aluminum oxide 46 to 60.

         3. The usual type of grinding wheel, that contains diamond particles, is one of an concentration of 100.

         4. The types of wheels used, for the usual abrasives are:

            Silicon carbide: I/K.

            Aluminum oxide: J/K.

            The coating and procedure used has an affect on the type of which you can chose.

         5. The types of wheel bonds used are:

            Diamond: Resinoid bond.

            Usual abrasives: Vitrified.

         6. Sufficient coolant must always be available, at the point where the wheel touches the coating surface. The coolants are usually water-base oils.

         7. The wheel speeds usually used are between 5.000 to 6.500 sfpm (1500 to 1900 m/min).

         8. The work speeds usually used are:

            Surface grinding 40 to 50 sfpm (12 to 15 m/min).

            Cylindrical grinding - (with the usual wheels) 80 to 250 sfpm (24 to 76 m/min).

            Cylindrical grinding - (with diamond wheels) 100 to 200 sfpm (30 to 61 m/min).

         9. The depth of cut is different, for each coating and procedure used, but must be in the range of:

            For surface grinding use a 'plunge' grinding rate of 0.00025 to 0.0005in./pass (0.006 to 0.013 mm/pass), with a movement or depth of cut of 0.00025 to 0.0005in./pass (0.006 to 0.013 mm/pass).

            For cylindrical grinding use a 'plunge' grinding rate of 0.003 to 0.005 in./min (0.075 to 0.13 mm/min) on the diameter, with a movement or depth of cut of 0.0005 to 0.001 in./pass (0.013 to 0.025 mm/pass).

         10. For surface grinding cross-feeds must not be too much. (That is 0.030 to 0.050 in./pass (0.75 to 1.30 mm/pass).)

         11. For cylindrical grinding the table movement rate is usually 0.050 to 0.10in./turn (1.30 to 2.50 mm/turn).

         12. Matt or glossy wheels give a more shinny and lower surface finish indication; than the same wheel used in a clean, free-cutting condition. The surface if examined with a lens (10x) will look dirty and heat damaged. The parts must be examined, during and after the grinding operations, for signs of defects that can not be accepted.

      3. Buffing.

         1. Coatings with a high carbide level can be used in the 'as sprayed' condition if the dimension tolerances permit. It is recommended that such coatings be made smooth by buffing, to remove all sharp points, which makes the assembly of mating parts easier.

         2. Soft coatings must always be machine finished, because buffing can cause the local removal of coating, which is not easily seen.

4. SUBTASK 70-34-01-340-004 Spraying Procedures for Abradable Coatings

   NOTE

   To keep the necessary quality standards the points that follow must be continuously monitored.

   1. Spraying must be effected as in Step.

      1. Powder supply rate.

      2. Gas flow and pressure.

      3. Spraying angle and distance.

      4. Spray gun to work piece movement rate.

         NOTE

         Always clean the gas and powder nozzles between spraying operations.

      5. Clean nozzles.

         NOTE

         If a hardness test can not be done on the part, the integral test piece procedure must be used. A 0.98 x 0.59 x 0.06 in. (25 x 15 x 1.6 mm) minimum steel test piece attached to and sprayed with the work piece.

         Details of the spraying data are given in Figure. The system is identified by SUBTASK and CoMat numbers for the materials being sprayed
