Analysis on the Causes of the Coating Falling of Cast Aluminum Alloy

Cast aluminum alloy parts have been widely used in modern industry due to their light weight, good electrical conductivity, low casting cost and easy processing. In high-voltage electrical products, conductor connections are generally required to be plated with silver to reduce contact resistance. Cast aluminum alloy parts are mostly used. However, due to the characteristics of the casting process, the surface of the material has coarse crystals, pores, and pores in the structure. Defects such as blisters, loose porosity, etc., cause poor adhesion of the silver-plated layer of cast aluminum alloy parts. Frequently, a certain proportion or batch of plating layer blisters and falls off, which causes the contact resistance of the conductor to increase, thereby affecting the conductivity of the conductor. Therefore, research on how to reduce the material defects of cast aluminum alloy parts and improve the quality of silver plating is of great significance to the high-voltage electrical industry. For general cast aluminum alloy parts, in addition to the key electroplating process, the material structure and structure of the parts It is also the key to get good adhesion coating for cast aluminum alloy parts. This article discusses the microstructure and chemical composition, and uses different processing methods to solve the problem of silver-plated cast aluminum alloy parts falling off.

In high-voltage electrical products, conductors often need to be silver-plated in multiple parts. Due to various reasons of the cast aluminum alloy parts themselves, it is difficult to ensure that all the coatings at all parts are qualified. Due to the different types and contents of elements contained in the cast aluminum alloy parts, there are Multiphase structure, the surface chemical composition is not uniform and the density is very different, especially there are microscopic casting shrinkage holes, blisters, looseness and other defects. During the silver plating process, the foreign matter in the micropores is not easy to clean, and the residual solution is again Return, causing the plating layer to blistering and falling off, and the rework rate of parts is high. Moreover, due to the phenomenon of pores, the gas and residual solution stored in the pores will corrode the surrounding metals and penetrate into The bonding part of the surface coating reacts with metal aluminum, zinc, etc., and the generated hydrogen causes quality defects such as peeling and shedding of the coating. Although water washing can reduce the residual electrolyte on the surface of the coating, the effect of repeated water washing is not obvious for the microscopic pores of the parts.
