Method No. 403G:耐磨涂层表面磨损修复

NOTE: Refer to manufacturer recommendations to know product shelf life of adhesive C01- 0001 and abradable coating compound C03-0001.

注：有关粘合剂C01- 0001和耐磨涂层化合物C03-0001的产品有效期，请参考制造商建议。

NOTE: Discard adhesive and compound that are more than product shelf life or becomes too thick to spread or handle without crumbling.

注：丢弃粘合剂和超过产品有效期的化合物，或变得过于稠厚而无法在不碎裂的情况下进行铺展或处理的化合物。

NOTE: Allow adhesive or compound to warm to room temperature prior to application. Refer to manufacturer recommendations. Discard remaining material, which was heated for application.

注：在应用前，使粘合剂或化合物升温至室温。请参考制造商建议。丢弃用于应用而加热的剩余材料。

Abradable coating surface wear repairs should be performed as follows:

应按如下步骤进行可磨涂层表面磨损修复：

WARNING: SOLVENT VAPORS ARE TOXIC AND FLAMMABLE. DO NOT INHALE. OBSERVE FIRE PRECAUTIONS.

警告：溶剂蒸气有毒易燃。请勿吸入。注意防火措施。

(1) Clean uncured adhesive and compound from application equipment. Use Toluene C08- 0018.

清洁应用设备上的未固化粘合剂和化合物。使用甲苯C08- 0018。

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。

(2) Machine surfaces to remove damage or remaining abradable coating. 100 percent clean up is necessary.

用机器表面去除损坏或剩余的可磨损涂层。必须进行100%的清洁。

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

(3) If necessary, perform magnetic particle or fluorescent penetrant inspection. No cracks permitted. Refer to SECTION III – INSPECTION. Refer to applicable manual.

必要时，进行磁粉或荧光探伤。不允许存在裂纹。请参阅第III节——检验。请参阅适用手册。

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

警告：请使用正确的个人防护装置。喷砂程序会产生松散颗粒，可能进入眼睛。

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。

(4) Grit blast areas to be coated to a uniform matte finish with aluminum oxide grit C04-0001.

用氧化铝砂粒C04-0001对喷砂区域进行涂覆，使其具有均匀的哑光表面。

(5) Clean part. Refer to SECTION II – CLEANING.

清洁部件。请参阅第II节-清洁。

(6) If surfaces are not immediately coated, cover prepared surfaces from contamination with clean paper.

如果表面没有立即涂覆，用干净的纸覆盖已准备好的表面以防止污染。

NOTE: Do not touch prepared surface with bare hands.

注：请勿用裸手接触已处理表面。

(7) Apply a thin coat of adhesive, C01-0001 of approximately 0.005 inch (0.13 mm) thick, to prepared surface with a spatula. Coating must have a rough surface texture before you apply the abradable coating compound.

用刮刀在准备好的表面上涂上一层厚度约为0.005英寸（0.13 mm）的粘合剂C01-0001。在涂覆可磨蚀性涂层化合物之前，涂层必须具有粗糙的表面纹理。

(8) Apply abradable coating compound C03-0001 over adhesive. Use pressure extrusion gun with special fan shaped extrusion nozzle. Apply on repaired surface more than 0.030 inch (0.76 mm) of necessary coating for finish machining.

在粘合剂上涂覆可磨蚀涂层化合物C03-0001。使用带特殊扇形挤出喷嘴的加压挤出枪。在修复表面涂覆超过0.030英寸（0.76 mm）的必要涂层，以便进行精加工。

(9) Lightly press coating surface. Use a spatula moistened with toluene C08-0018. Drag spatula over coating surface at a slight angle.

轻轻按压涂层表面。使用涂有甲苯的刮刀C08-0018。以轻微角度拖动刮刀在涂层表面。

NOTE: Do this procedure to make sure that there is contact between the abradable coating compound and adhesive.

注：执行本步骤以确保可磨损的涂层化合物与粘合剂之间存在接触。

(10) Cure abradable coating at 225 to 275˚F (109 to 135˚C) for two hours. Then cure for one more hour at 325 to 375˚F (163 to 191˚C).

在225至275˚F（109至135˚C）下固化耐磨涂层两小时。然后在325至375˚F（163至191˚C）下再固化一小时。

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。

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

机器表面的加工尺寸。有关修复限度，请参阅适用手册。

(12) Check abradable coating as follows:

按如下方法检查耐磨涂层：

(a) Visually check abradable coatings for uniformity in color, texture, and composition.

目视检查耐磨涂层的颜色、纹理和成分是否均匀。

(b) Check appearance of dark spots or streaks in coating with a metal probe to determine cure. Coatings with soft spots are not permitted.

用金属探针检查涂层中是否出现黑斑或条纹，以确定固化情况。不允许存在软斑的涂层。

(c) Visually check coatings for voids. Voids more than one-quarter inch in size maximum or closer than one inch are not permitted. Groups of smaller voids are acceptable.

目视检查涂层是否存在孔洞。孔洞最大尺寸不得超过四分之一英寸，或小于一英寸。允许多个较小的孔洞。

(13) Abrade and prepare areas that contain no permitted voids. Use a wire brush.

打磨并处理不含允许孔洞的区域。使用钢丝刷。

(14) Clean the part and let dry. Refer to SECTION II – CLEANING.

清洁部件并使其干燥。请参阅第II节-清洁。

(15) Use a spatula and fill voids with abradable coating compound C03-0001. Make sure not to collect air. Fill void with sufficient compound for finish machining.

使用刮刀，用可磨蚀性涂层化合物C03-0001填充孔洞。确保不收集空气。用足够的化合物填充空隙以完成加工。

(16) Cure abradable coating at 225 to 275˚F (109 to 135˚C) for two hours. Then cure for one more hour at 325 to 375˚F (163 to 191˚C).
