Application of aluminum alloy plating

As the aluminum hub of car safety, not only need to bear the weight and overload pressure of the vehicle during the course of the vehicle, but also require a longer running time than the whole car. Wheel hub in the aspect of balance of the whole car beautiful shape also play an important role, so the wheel hub surface treatment technology in improving the wheel hub corrosion resistance, improve the effect of stone resistance and increase the beautiful, etc., all becomes very important. At present, the surface processing technology of aluminum alloy wheel hub is mainly divided into coating (spray paint or powder) and electroplating, and the past simple anodic coating process has been phased out.

The aluminum wheel hub was first developed in the United States, and the luxury car with such a wheel is gorgeous and different, mainly because of the perfect combination of aluminum light and decorative chrome appearance. Chromium plating process main process is: the oil removal - cleaning - acid corrosion - pre galvanized - dark nickel plating to advance bright copper plating, cleaning - activation - nickel sealing to chrome plating, to blow water, dry cleaning, plating equipment can be used continuously through electrophoresis tank type or step by step, but the traditional electroplating process due to the use of strong acid, strong alkali and cyanide and chromium anhydride, poisonous and harmful chemicals such as wastewater composition is complicated, the great influence to the environment. With the strengthening of environmental protection consciousness society, vigorously develop green products can promote economic development, any sacrifice the development of environmental protection and waste of resources are only temporary, so in recent years, both at home and abroad have stepped up the study of aluminum wheel hub surface treatment, new technology, new technology also emerge in endlessly.

In addition, aluminum alloy because of low density, higher than strength, can adopt the die casting technology of high speed production size high precision and complicated shape and light quality of parts and components, to gain widespread use in areas such as aerospace and construction
