The surface of the hydraulic rod is chromium, and it often causes strain, scratch, electric shock and so on. The routine method is slow to repair and the effect is not satisfactory. Don't want to play with copper, also do not want to use cold, patch method, because of poor adhesion, never long broken. Is there a better way to fix it?
Compared with welding repair technology, the problems of local high temperature will not occur. Electroplating repair technology is the use of electrolysis principle, the bath metal ions reduced to metal atoms, and deposited on the metal surface, forming a high binding force and a certain thickness of the repair layer.
Brush plating method to repair hydraulic rod, cylinder pull, the best effect. Because the 1. can be repaired on the spot, the trouble of loading and transporting is avoided. 2., coating adhesion is good, no obvious boundaries, repair surface hardness, good wear resistance. 3. low temperature operation will not change the properties of the substrate. Electroplating repair technology is a kind of traditional repair technology to restore the size of parts at low temperature.
Although there are many kinds of electroplating, there are two main types that can be used for repair, namely, low temperature iron plating and thick chromium plating. Because the deposition rate is slow and the production efficiency is low, people often use the low temperature iron plating technology. In order to improve the corrosion resistance and wear resistance of the iron coating, the surface of the iron coating is usually plated with a thin layer of chromium.
