Procedure

    1. SUBTASK 72-32-83-350-070 Remove the Damage

    1. Refer to Figure and Figure.

      2. CAUTION

        WHEELS, STONES AND ABRASIVE PAPERS USED TO DRESS, MAKE SMOOTH, OR POLISH A TITANIUM COMPONENT MUST BE OF THE SILICON CARBIDE TYPE. ALUMINUM OXIDE TYPES MUST NOT BE USED.

        CAUTION

        IF MECHANICAL CUTTERS ARE USED, ONLY SMALL CUTS MUST BE MADE TO PREVENT TOO MUCH HEAT.

        Scallop, make smooth and/or hand polish to remove nicks, scratches and damage.

      1. Use abrasive stones or papers and/or fine file.

      2. Use light pressure to prevent risk of overheating the material.

      3. All polish marks must be in a radial direction from the vane ID to OD.

      4. The surface finish of the repair area must be the same as the adjacent area.

      3. Hand polish the vane leading and/or trailing edge radius and the vane profile to make a smooth shape.

      2. Remove the minimum quantity of material necessary to give the correct radius.

      3. Refer to the SPM TASK 70-35-03-300-501.

    2. SUBTASK 72-32-83-220-158 Visually Examine the Repair

    1. Refer to Figure and Figure.

      2. Do a visual and dimensional inspection.

      1. Visually examine the repaired area for nicks, scratches and damage.

      2. Use a 10X magnifying glass.

      3. Refer to TASK 72-32-83-200-000 (INSPECTION-000).

    3. SUBTASK 72-32-83-230-072 Do a Crack Test

      1. Do a penetrant crack test.

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

      2. Refer to TASK 72-32-83-200-000 (INSPECTION-000).

      3. Cracks are not permitted.
