What is the best way to repair hydraulic shaft scratches?

Brush plating method to repair hydraulic rod, cylinder of the strain, the best effect.

1. can be repaired on site, eliminating the trouble of loading transportation.

2. Coating bonding Force is good, no obvious boundary, repair surface hardness is high, wear resistance is good.

3. Low temperature operation, will not change the substrate properties. Electroplating Repair technology is a traditional repair technology to restore the size of parts under low temperature, and there will be no problems caused by local high temperature compared with welding repair technology. Electroplating Repair technology is to use the principle of electrolysis to reduce the metal ions in the plating solution into metal atoms and deposited on the metal surface to form a high binding force and a certain thickness of the repair layer. Although there are many types of electroplating, there are two main types that can be used for repair, namely low-temperature iron plating and thick chromium plating. Because of the slow deposition rate and low production efficiency, the low-temperature iron plating repair technology is used in the process of chromium plating. In order to improve the corrosion resistance and abrasion resistance of the iron plating layer, a thin layer of chromium is usually deposited on the surface of the iron plating layer. For hydraulic rods, cylinders, such as working in the outdoor parts, with low-temperature iron plating recovery size, after grinding the surface cover chromium is the most commonly used repair method.
