Procedure

    1. SUBTASK 72-50-23-325-055 Machine the Radial Dimension D1

      NOTE

      If the shroud seal segment was plasma spray repaired before remove the old coating fully.

      1. Machine the radial dimension D1.

      1. Use IAE 3M14261 Turning fixture 1 off and vertical turning lathe.

        Refer to Figure.

        Remove old coating and damage fully. Keep material removal to the minimum to allow subsequent repairs.

    2. SUBTASK 72-50-23-220-084 Examine the Machined Surface

      1. Dimensionally examine.

      1. Refer to Figure.

        Write down the radial dimension D1.

        Use radius gage set and dial caliper.

    3. SUBTASK 72-50-23-230-067 Examine the Machined Surface for Cracks

      1. Do the test for cracks.

      1. Refer to the SPM TASK 70-23-05-230-501.

        No cracks are permitted.

    4. SUBTASK 72-50-23-110-062 Clean the Shroud Seal Segment

      1. Vapor degrease.

      1. Refer to the SPM TASK 70-11-01-300-503.

    5. SUBTASK 72-50-23-340-057 Prepare the Surfaces for the Plasma Spray Procedure

      1. Mask the areas A3.

      1. Install the shroud seal segment on to the base plate.

        Refer to Figure.

        Make sure that the surfaces have full protection.

      2. Grit blast the area A1.

      1. The surface texture must be 120 to 200 microinch RMS (3.0 to 5.0 micrometer ra). Blasting in area A2 is permitted.

        Refer to Figure.

        Refer to the SPM TASK 70-23-03-340-501.

        Use roughness microtester.

      3. Replace the masking if necessary.

      1. Remove masking fixtures.

        Make sure that the silicone rubber cover is installed correctly. Replace damaged heat reflective tape or high temperature tape if used. Do not touch or bring unwanted material on the blasted areas.

    6. SUBTASK 72-50-23-340-058 Plasma Spray the Prepared Surface

      1. Plasma spray the area A1.

      1. Install IAE 3M14277 Masking fixture 1 off and IAE 3M14344 Masking fixture 1 off with the shroud seal segment on to turntable.

        Overspray in area A2 is permitted.

        Refer to Figure.

        Make sure that there is sufficient material sprayed on to do last machining.

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

    7. SUBTASK 72-50-23-340-059 Remove the Protection from the Masked Surfaces

      1. Remove all masking.

      1. Remove masking fixtures, silicone rubber cover or heat reflective and high temperature tape. No masking is permitted.

    8. SUBTASK 72-50-23-110-063 Clean the Shroud Seal Segment

      1. Vapor degrease.

      1. Refer to the SPM TASK 70-11-01-300-503.

    9. SUBTASK 72-50-23-325-057 Machine the Radial Dimension D2

      1. Machine the coated area and chamfer.

      1. Overspray in area A2 to be removed fully.

        For dimensions refer to Figure.

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

        Use vertical turning lathe.

    10. SUBTASK 72-50-23-110-064 Clean the Shroud Seal Segment

      1. Vapor degrease.

      1. Refer to the SPM TASK 70-11-01-300-503.

    11. SUBTASK 72-50-23-220-085 Do the Post Repair Inspection

      1. Dimensionally examine the machined area.

      1. To calculate the coating thickness subtract the radial dimension D2 from the radial dimension D1.

        Refer to Figure.

        Use dial caliper, external micrometer and roughness microtester.

      2. Examine the coating.

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

    12. SUBTASK 72-50-23-350-055 Make a Mark to Identify the Repair

      1. Vibropeen VRS4105 and applicable beehive symbol adjacent to the part number.

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