飞机硬铝构件表面划伤的电刷镀快速修复

Rapid Restoration of Scuffed Surface of Aircraft Parts Made of Hard-Aluminum Alloy by Brush Electroplating

为解决飞机上硬铝材料零件局部损伤后的修复难题,对电刷镀技术在飞机铝合金零部件表面局部划伤的修复进行了可行性研究。初步探讨了快速修复的工艺流程及工艺规范,对修复后零件的硬度、结合力和耐磨性进行了测定。结果证明:飞机硬铝构件表面划伤的电刷镀修复工艺流程简单、操作方便、成本低,镀层与基体金属的结合强度高,镀层质量满足性能要求,有较好的推广价值。

The feasibility to restore the local scuffed surface of aircraft parts made of hard-aluminum alloy by making use of brush electro-plating was explored. The technological process and condition for the rapid restoration were preliminarily investigated. The hardness, adhesion strength, and antiwar performance of the brush electropla-ted coating were measured. Results show that the brush electropla-ting process for restoring the scuffed surface of aircraft parts made ofhard-aluminum alloy has the advantages of simple procedure, easy operation, and low cost. The resulting coating is well adhered to the substrate and meets with the requirement for the rapid repair of the locally scuffed hard-aluminum alloy parts of aircrafts. In one word, the present process may find promising application in the sur-face engineering of aircraft parts made of hard Al alloy.
