The conventional method of swinging the oil cylinder strain is slow to repair, and the effect is not ideal; the method of copper nailing, cold welding and patching method is not long because of the poor binding force. In fact, the ideal method is to repair it by brush plating. Because: 1. It can be repaired on site, eliminating the trouble of loading and transportation. 2. The coating has good bonding strength, no obvious boundaries, high hardness of the repair surface and good wear resistance. 3. Low temperature operation will not change the properties of the substrate. Electroplating repair technology is a traditional repair technology that restores the size of parts under low temperature conditions. Compared with welding repair technology, there are no problems caused by local high temperature. The electroplating repair technology uses the principle of electrolysis to reduce the metal ions in the plating solution to metal atoms and deposit them on the metal surface to form a repair layer with high binding force and a certain thickness. 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. Due to the slow deposition speed and low production efficiency during chrome plating, people often use low-temperature iron plating repair technology. In order to improve the corrosion resistance and abrasion resistance of the iron plating layer, a thin chromium layer is usually plated on the surface of the iron plating layer. For components such as oil cylinders that work outdoors, low-temperature iron plating is used to restore the size, and the surface is covered with chromium after repairing, which is a relatively common repair method. The above is the introduction of the ideal repair method for the swing oil cylinder strain. The word method can also be used to repair the hydraulic rod, and the effect is very good.
