WARNING

IT IS THE RESPONSIBILITY OF THE OPERATOR TO OBTAIN AND OBSERVE THE MANUFACTURER'S SAFETY DATA SHEETS FOR CONSUMABLE MATERIALS INFORMATION (SUCH AS HAZARDOUS INGREDIENTS, PHYSICAL/CHEMICAL CHARACTERISTICS, FIRE HAZARD DATA, EXPLOSION HAZARD DATA, REACTIVITY HAZARD DATA, HEALTH HAZARD DATA, PRECAUTIONS FOR SAFE HANDLING, USE AND CONTROL MEASURES), AND ALSO TO TAKE LOCAL REGULATIONS INTO CONSIDERATION.

CAUTION

IF YOU PUT A HOOK THROUGH A TIEROD HOLE OR BALANCE HOLE OF A DISK, HUB OR DRUM WHEN PLATING A PART, THE HOOK CAN CAUSE DAMAGE THAT CAN CAUSE PART FAILURE DURING ENGINE OPERATION.

Procedure

1. General Instructions

   1. Procedure And Operations

      1. The applicable TASK gives the correct procedure and the operations. You can change the operations for chemical and electrolytic surface treatment only when International Aero Engines AG permits the change.

   2. Plating personnel must be properly trained so they are fully knowledgeable with the TASKS that they perform in their department. They must also be knowledgeable of the general plating information that is in this section. Lack of proper training can result in damage to parts and/or coatings or the scrapping of parts. Adequate equipment and close control of solutions and operations is also necessary for satisfactory plating results.

   3. Condition Of Components

      1. Before surface treatment, components must be clean and without corrosion. They must not have grease, unwanted material or fingerprints on them. Always wear clean gloves when you touch clean components.

   4. Protection Of Surfaces That Will Have No Surface Treatment

      1. You must protect the surfaces that will have no surface treatment. Use approved materials such as wax, masking tape and wax, lacquer, masks or fixtures.

   5. Jig Components

      1. Jig components that are to have electrolytic surface treatment, this will give good electrical contact. These contacts must cause no local increase in temperature, sparks or chemical deposits. If possible, use surfaces that will not have surface treatment, for the contacts. Remove surface layers that are not conductors with the applicable abrasive. Do not permit the components to touch and prevent mechanical damage (electrical arcing, burning).

   6. Bath Instructions

      1. Soak the components so that the areas for surface treatment are wet.

      2. If you do not obey the specified times for treatment, damage to the component could occur.

   7. Cold Water Rinse

      1. Shake the components when you put them in the cold water bath. You can also flush them with a cold water spray.

      2. If a rinse time is specified with no range or tolerance, the specified rinse time is the minimum rinse time.

   8. Hot Water Rinse

      1. When you put the components in the hot water bath, they must stay there until their temperature increases sufficiently to flash dry.

      2. Solution temperature gages

         1. Use temperature gages on tanks used for solutions or water for which heat is necessary.

         2. Calibrate gages at regular intervals to be sure of a correct calibration to a standard derived from the National Institute of Standards and Technology or to a standard specified by the equipment manufacturer. If the equipment was made by a manufacturer from a country other than the U.S.A, use the standard of the country of origin if approved by the Administrator. Verify one time each day that the gages are in satisfactory working condition.

         3. If a rinse time is specified with no range or tolerance, the specified rinse time is the minimum rinse time.

   9. Air-Water Gun

      1. You can use an air-water gun to wash the component. For best results, do this immediately after you remove the component from the bath. To prevent corrosion, make sure you fully remove the bath solution from all empty spaces in the component.

   10. Dry With Compressed Air

       1. Dry the components with clean compressed air. Make sure water is removed from all empty spaces in the component.

   11. Plating Process Heat Treatment

       1. If a plating procedure specifies a heat treatment time with no range or tolerance, the specified heat treatment time is the minimum time.

2. Special Instructions

   1. Titanium Components

      1. You can damage titanium if it touches parts made of cadmium, bismuth, lead, tin, zinc, gold or silver. Do not use tools that have these materials in them or on them. Be careful when you touch titanium parts; keep rings, watches and buckles away from the parts.

      2. Use only the materials specified by International Aero Engines AG for the surface treatment of titanium.
