The aircraft flap slide is a vulnerable part,due to that it is often worn out during work and the chromium coating on the working surface is peeled off.In order to reduce the maintenance cost and to shorten the maintenance period,the thickness and the surface roughness of chromium coating on the surface of the flap slide are needed to reach the design state through the design of special electroplating tooling and appropriate electroplating process.The successful repair of this part has certain reference significance for the design of pictographic anode design and process parameters of chrome electroplating tooling for other different parts.
