5.Removing Damage from Steel Parts
清除钢制零件上的损伤
A.Method No. 405A: Minor Surface Defect Repair
Method No. 405A:微小表面缺陷修复
Repair minor surface defects on steel parts as follows:
按如下方式修复钢零件上的轻微表面缺陷：
NOTE: Remove minor surface defects only if the defect is detrimental to operation and removal will not cause or increase leakage or compromise sealing functions.
注：仅当表面轻微缺陷对操作有害且去除缺陷不会导致或增加泄漏或破坏密封功能时，才可去除该表面缺陷。
WARNING: DO NOT BREATHE THE PARTICLES FROM BLENDING OR LET THE PARTICLES TOUCH YOU. PARTICLES FROM BLENDING CAN CAUSE DAMAGE, INJURY, OR IRRITATION TO YOU. USE PERSONAL PROTECTION EQUIPMENT. USE LOCAL MECHANICAL EXHAUST VENTILATION OR AN APPROVED RESPIRATOR.
警告：请勿吸入过渡（打磨）产生的颗粒物或让颗粒物接触身体。过渡（打磨）产生的颗粒物可能导致损伤、伤害或刺激身体。请使用个人防护设备。请使用本地机械排气通风装置（就是说工作区域要有通风设备，什么样子的都行）或经批准的呼吸器。
(1) Blend minor burrs, galling, pitting, scratches, or sharp edges to get a smooth transition with the surface. Refer to applicable manual for Repaired Limits.
打磨过渡轻微的毛刺、擦伤、凹坑、划痕或锐边，以获得与表面平滑过渡。请参阅适用的手册中的“修复限制”。
(a) Blend compressor rotor blades, stator vanes, turbine blades, diffuser vanes, and similar parts in a radial direction in relation to the engine.
将混合压缩机转子叶片、定子叶片、涡轮叶片、扩压器叶片和类似零件按相对于发动机的径向方向进行打磨过渡。
NOTE: Make sure trailing and leading edges of airfoil section do not become thin or sharp to conform to the original contour.
注：确保机翼截面的后缘和前缘不会变薄或变得尖锐，以符合原始轮廓。
(b) Blend cylindrical parts in a circumferential direction.
沿圆周方向打磨圆柱形零件
NOTE: Make sure not to blend along the axis of the part.
注：请确保不要沿着零件的轴线进行打磨过渡。
(2) If the repaired part involves a radius, keep radius as specified in applicable manual.
如果修理的零件涉及半径，请按适用手册中的规定保留半径。
(3) Provide a surface finish as specified in applicable manual.
提供（保证）适用手册中规定的表面光洁度。
