The application of aluminum alloys in the industrial field has increased year by year. However, there are still some problems in the use of aluminum components, mainly due to poor wear resistance. The reason is that the hardness is low, the friction coefficient is high, the wear is large, it is easy to be injured and it is difficult to lubricate. The second is that the strength is not easy to deform, and it is easy to be corroded in the presence of alkaline media and chloride ions, which limits the further application of aluminum. Shanghai Minjian Aluminum Co., Ltd. has found a set of effective ways to deal with the surface hardening of aluminum alloys through the joint research of the company's technology center and Central South University. We believe that aluminum alloy anodizing is an effective method to solve the above problems. Among them, hard anodizing can improve the corrosion resistance, wear resistance, heat resistance and insulation of aluminum parts. It can reach tens or even hundreds of μm, thickness is easy to control, and high dimensional accuracy. Many workpieces can be directly assembled and used after processing. The film layer has micropores, can absorb various lubricants, withstand breakdown voltage up to 2000V, combined with the substrate It is strong, so it has a wide range of application prospects in the fields of aviation, aerospace, ship, automobile, motorcycle, electronics, instrumentation, textile and machinery industry.
