F.Method No. 403F: Plasma Spray Repair

Method No. 403F：等离子喷涂修复

NOTE: Electric Arc Metallizing may be used as an alternative method to Plasma Spray Repair.

注：电弧金属化可作为等离子喷涂修复的替代方法。

WARNING: USE THE CORRECT PERSONAL PROTECTION. PROCEDURES THAT NEED GRIND/MACHINE WORK WILL CAUSE LOOSE PARTICLES THAT CAN GET IN YOUR EYES.

警告：使用正确的个人防护设备。需要研磨/机械加工的程序会产生松散颗粒，可能进入眼睛。

(1) Machine surfaces to remove damage or all remaining plasma spray. 100 percent clean up is necessary.

清理机器表面的损坏或所有残留的等离子喷涂。必须进行彻底清理。

NOTE: Make sure minimum stock material is removed. Do not machine more than the limits specified in applicable manual.

注：确保移除最低堆积材料。请勿加工超过适用手册中规定的限制。

(2) If necessary, perform magnetic particle or fluorescent penetrant inspection. No cracks are permitted. If you find cracks replace the part. Refer to SECTION III – INSPECTION.

必要时，进行磁粉或荧光探伤检查。不允许存在裂纹。如果发现裂纹，则更换零件。参见第III节——检查。

NOTE: Do these inspection procedures only for rotating components. Refer to applicable manual.

注：这些检查程序仅适用于旋转部件。请参阅适用手册。

(3) Clean the part. Refer to SECTION II – CLEANING.

清洁部件。请参阅第II节-清洁。

CAUTION: EXERCISE CARE IN MASKING AND SEALING OF PARTS TO MAKE SURE THAT ALL AIR/OIL PORTS, STRUCTURAL OPENINGS, AND RELATED SURFACES OF PARTS ARE PROTECTED FROM OVERSPRAY.

注意：小心地对零件进行遮蔽和密封，以确保所有空气/油口、结构开口和零件的相关表面都受到保护，避免过度喷溅。

(4) Mask all areas not to be grit blasted.

遮盖所有不需要喷砂处理的区域。

NOTE: Do not use metal abrasive alloys for grit blast process.

注：请勿在喷砂处理过程中使用金属磨料合金。

WARNING: USE THE CORRECT PERSONAL PROTECTION. GRIT BLAST PROCEDURES WILL CAUSE LOOSE PARTICLES THAT CAN GET INTO YOUR EYES.

警告：请使用正确的个人防护设备。喷砂程序会产生松散颗粒，可能进入您的眼睛。

CAUTION: DO NOT DISTORT PART DURING GRIT BLAST PROCESS.

注意：喷砂处理过程中，切勿使零件变形。

(5) Grit blast areas to be plasma sprayed to a uniform matte finish with aluminum oxide grit C04-0001.

用氧化铝砂粒C04-0001对喷砂区域进行等离子喷涂，使其具有均匀的哑光表面。

NOTE: Plasma spray process must be applied no more than 2 hours after grit blast. If more time passed, the part must be grit blasted again.

注：等离子喷涂工艺必须在喷砂处理后2小时内进行。如果超过该时间，必须对零件再次进行喷砂处理。

(6) Clean part to remove blasting material. Refer to SECTION II – CLEANING.

清洁零件以去除喷砂材料。请参阅第II节-清洁。

(7) If necessary, mask again all surfaces not to be plasma sprayed.

如有必要，再次对所有表面进行遮蔽，以避免等离子喷涂。

WARNING: USE THE CORRECT PERSONAL PROTECTION. HEATED PARTS WILL CAUSE BURNS.

警告：使用正确的个人防护装置。加热部件会造成灼伤。

(8) If necessary, preheat part before application of plasma spray bond coat. Refer to applicable manual.

必要时，在应用等离子喷涂粘合涂层前对零件进行预热。请参考适用手册。

WARNING: USE THE CORRECT PERSONAL PROTECTION. PLASMA SPRAY CAN CAUSE SKIN, EYE AND LUNG DAMAGE.

警告：请使用正确的个人防护设备。等离子喷涂可能造成皮肤、眼睛和肺部损伤。

CAUTION: IF SURFACES ARE NOT TO BE PLASMA SPRAYED IMMEDIATELY, BLASTED SURFACES MUST BE PROTECTED FROM CONTAMINATION UNTIL COATING IS APPLIED.

注意：如果表面不能立即进行等离子喷涂，则喷砂处理的表面必须在涂装前避免污染。

(9) Apply plasma spray to surfaces with sufficient thickness for final machining. Refer to applicable manual for required coating thickness.

在具有足够厚度的表面上施加等离子喷涂，以便进行最终加工。有关要求的涂层厚度，请参考适用的手册。

WARNING: BEFORE REMOVAL OF MASKING MATERIAL, LET TEMPERATURE OF PART TO SLOWLY DECREASE TO ROOM TEMPERATURE OR AS SPECIFIED IN APPLICABLE MANUAL. HEATED PARTS WILL CAUSE BURNS.

警告：在去除遮蔽材料之前，应使零件温度缓慢降低至室温或适用手册中规定的温度。加热的零件会造成灼伤。

(10) Remove masking material.

移除遮蔽材料

WARNING: BEFORE REMOVAL OF MASKING MATERIAL, LET TEMPERATURE OF PART TO SLOWLY DECREASE TO ROOM TEMPERATURE OR AS SPECIFIED IN APPLICABLE MANUAL. HEATED PARTS WILL CAUSE BURNS.

警告：在去除遮蔽材料之前，应使零件温度缓慢降低至室温或适用手册中规定的温度。加热的零件会造成灼伤。

(11) Machine surface to finish dimensions. Refer to applicable manual for repaired limits.

机械加工表面到表面处理尺寸。有关修复限制，请参阅适用手册。

(12) Deburr and remove all overspray as necessary.

去除毛刺，并在必要时清除所有多余喷物。
