Repair minor damage to magnesium-alloy parts as follows:

镁合金零件的轻微损坏修复方法如下：

WARNING: USE THE CORRECT PERSONAL PROTECTION. THIS CHEMICAL SOLUTION CAN CAUSE SKIN EYE, AND LUNG DAMAGE. THE DANGER AND PRECAUTIONS FOR EACH CHEMICAL IS DIFFERENT.

警告：请使用正确的个人防护装备。该化学溶液可能对皮肤、眼睛和肺部造成伤害。每种化学品的危险性及防护措施各不相同。

CAUTION: MAKE SURE TO OVEN DRY THE PART AT 250°F (121°C) FOR TWO HOURS, IMMEDIATELY AFTER CLEANING.

注意：清洁后请立即用250华氏度（121摄氏度）的烘箱箱烘干部件两小时。

(1) Hand finish damaged areas to remove raised metal.

对受损区域进行手工处理，以去除凸起的金属。

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

清洁部件。参见SECTION II – CLEANING。

(3) Mask all areas not to be repaired.

遮蔽所有不需要修复的区域。

CAUTION: DO NOT EXCEED TEMPERATURE LIMITATIONS DURING CURE PERIOD.

注意：固化期间温度不得超过限制。

(4) Before application, increase temperature of Epoxy Paste Adhesive C01-0002 to room temperature, or increase temperature of compound to 110°F (43°C) maximum. Discard unwanted compound that was heated for thinning purpose.

使用前，需将环氧树脂胶粘剂C01-0002升温至室温，或使化合物温度升至最高110华氏度（43摄氏度）。丢弃用于稀释目的而加热的不需要的化合物。

NOTE: Keep compound refrigerated at least 40°F (5°C) to extend the shelf life. Discard if compound is out of shelf life (six (6) months) or becomes too thick to apply without crumbling.

注意：将化合物冷藏至至少40华氏度（5摄氏度）以延长保质期。若化合物超过保质期（六个月）或因过稠而无法涂抹时，请丢弃。

NOTE: Uncured Epoxy Paste Adhesive C01-0002 can be cleaned from work area and application equipment using denatured alcohol.

注：未固化的环氧树脂粘合剂C01-0002可使用变性酒精从工作区域和应用设备中清除。

CAUTION: EXERCISE CARE IN APPLYING COMPOUND TO MINIMIZE THE TRAPPING OF AIR.

注意：使用化合物时应小心谨慎，以尽量减少空气的接触。

(5) Apply compound with sufficient thickness for finish machine. Use a spatula for compound application.

使用厚度足够的化合物进行表面处理，应用刮刀涂抹腻子。

NOTE: Uncured adhesive can be cleaned from work area and application equipment using denatured alcohol.

注：未固化的粘合剂可用变性酒精从工作区域和应用设备中清除。

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

警告：请正确佩戴个人防护装备。高温零件可能导致烫伤。

(6) Cure compound in an oven for one hour at 350°F (177°C).

将化合物放入烘箱中，在350华氏度（177摄氏度）下烘烤一小时。

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

警告：请使用正确的个人防护措施。需要进行研磨或机械作业时，会产生松散颗粒，可能进入眼睛。

(7) Machine part to finish dimensions. Refer to applicable manual for repaired limits.

机加工零件到最终尺寸。请参阅适用手册以了解修复后的限制。

(8) Check machined part as follows.

按如下所示检查机加工零件。

(a) Porosities or voids of 0.015 inch (0.381 mm) minimum must be considered as related. Porosities or voids less than 0.015 inch (0.381 mm) must not be considered during evaluation.

孔隙或空隙最小值必须为0.015英寸（0.381 mm），否则视为相关。孔隙或空隙小于0.015英寸（0.381 mm）的，不得在评估中考虑。

(b) Porosities or voids of 0.080 inch (2.032 mm) maximum diameter are permitted. Two 0.080 inch (2.032 mm) porosities or voids or any number of smaller porosities or voids with a combined area no greater than two 0.080 inch (2.032 mm) within a 0.50 X 0.50 inch (12.7 X 12.7 mm) area is permitted.

允许存在最大直径为0.080英寸（2.032 mm）的孔隙或空隙。允许在0.50 X 0.50英寸（12.7 X 12.7 mm）区域内存在两个0.080英寸（2.032 mm）的孔隙或空隙，或存在任意数量的较小孔隙或空隙，但其总面积不得超过两个0.080英寸（2.032 mm）的孔隙或空隙。

不允许出现孔隙、空隙或母体金属碎裂。

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

清洁部件。参见SECTION II – CLEANING。

CAUTION: EXERCISE CARE IN APPLYING COMPOUND TO MINIMIZE THE TRAPPING OF AIR.

注意：使用化合物时应小心谨慎，以尽量减少空气的接触。

(10) If necessary, apply compound to porosity and/or voids with sufficient thickness for finish machine.

必要时，应将化合物涂覆于孔隙和/或空隙处，厚度需足够以满足表面精度加工的要求。

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

警告：请正确佩戴个人防护装备。高温零件可能导致烫伤。

(11) Cure compound in an oven for one hour at 350°F (177°C).

将化合物放入烘箱中，在350华氏度（177摄氏度）下烘烤一小时。
