Inside the surface:
Made of aluminum alloy material handicraft generally are required to have the appearance of bronze color or gold, low-grade products are mostly used in dyeing, such as dyeing bronze, dyed golden yellow. Some of the arts and crafts are the use of antique copper plating or imitation gold plating. High - grade handicrafts must be used with hard gold plating. Due to the low potential of aluminum alloy material, and pro oxygen ability is strong, the moment that is able to generate natural passivation film, and in the plating solution due to the potential negative and easily occurred replacement reaction, so direct plating coating binding force range, so aluminum alloy before plating must preprocess, otherwise can't get a good coating. The pretreatment method has a variety of, dip replacement method is used widely, such as leaching zinc, tin, iron, nickel and other metals and alloys. Many foreign companies have this aspect of the use of patents and supply of goods. There are also research and development of this kind of product and application in production. Here Yang Zhongdong, Li Changye, who developed the dip pre processing technology and aluminum silicon alloy casting crafts decorative gold plating process in production applications. Production and application of products for pressing aluminum silicon alloy manufacture sun bird, has been used for many years, according to the golden film still bright unabated, combined with strength and good corrosion resistance.
