    5. SUBTASK 72-50-22-340-031 Prepare the Surfaces for the Plasma Spray Procedure

      1. Mask the areas A1, A2 and A3.

      1. Make sure that the surfaces have full protection. Use CoMat 02-047 TAPE, HEAT REFLECTIVE or CoMat 02-050 HIGH TEMPERATURE GLASS CLOTH TAPE.

        Refer to Figure.

      2. Grit blast the area A4.

      1. Use grit blast equipment. Use CoMat 05-046 ALUMINUM OXIDE GRIT. The surface texture must be 120 to 200 microinch (3.0 to 5.0 micrometer ra).

        Refer to Figure and to the SPM TASK 70-34-03-340-501.

      3. Change the masking if necessary.

      1. Replace the damaged masking if required.

    6. SUBTASK 72-50-22-340-032 Plasma Spray the Prepared Surface

      1. Plasma spray the area A4.

      1. Use control unit, horizontal and vertical transvers unit. Use turntable, turntable control assembly and transvers unit control assembly.

        Use plasma spray equipment.

        The coating thickness must be 0.004 to 0.013 in. (0.11 to 0.32 mm) and must agree with the required flange thickness. Refer to Figure.

        Coating optional and must not be complete in areas A1, A2, A3 and A5. Refer to Figure and Figure.

    7. SUBTASK 72-50-22-340-033 Remove the Protection from the Masked Areas

    9. SUBTASK 72-50-22-220-370 Do the Post Repair Inspection

      1. Dimensionally examine the coated area.

      1. Refer to Figure.

        Use dial caliper, micrometer and roughness micro-tester.

      2. Examine the coating.

      1. Refer to the SPM TASK 70-34-03-340-501-002 for acceptance standards.

    10. SUBTASK 72-50-22-380-088 Make a Mark to Identify the Repair

      1. Vibropeen VRS4430 and applicable beehive symbol adjacent to the part number.

      1. Refer to the SPM TASK 70-09-00-400-501.

        Use a vibrating marking pencil.
