Surface anti-corrosion technology of aluminum alloy shell parts

2022-07-21

Aluminum alloy has very active properties and is easy to form oxide film on its surface, which is difficult to be electroless plated on its surface under conventional conditions. Generally, nickel is plated on the surface of aluminum alloy first, and then other elements are plated.

There are two methods most widely used in chemical nickel plating process: zinc immersion pre plating method and direct chemical nickel plating method. The disadvantage of zinc immersion pre coating method is that it is easy to cause the nickel layer to peel off in a humid corrosive environment. Electroless plating can improve the corrosion resistance and service life of products, and also improve the wear resistance and lubricity of machined parts.

Therefore, it has become the development trend of surface treatment technology. Thermal spraying technology can spray a variety of metal alloys and non-metallic and other solid materials, so it can be made into functional coatings with various properties, and the construction is flexible and adaptable.The surface anti-corrosion treatment shell greatly improves the performance of aluminum alloy shell parts. In order to further meet the anti-corrosion requirements, the surface needs to be sprayed with paint. With the increasing requirements of environmental protection, people's awareness of environmental protection is increasing, and the coatings used for surface corrosion prevention are developing towards the direction of no pollution or low pollution.

With the development of manufacturing technology of various aluminum alloy products, coatings with anti-corrosion function are playing an increasingly important role in saving, environmental protection, anti-corrosion and so on. With the increasing expansion and improvement of the application scope and quantity of aluminum alloy shell parts, the surface corrosion prevention of aluminum alloy shell has also been paid more and more attention by various industries. The research and development and improvement of aluminum alloy surface corrosion prevention technology has become the focus of the aluminum alloy shell processing industry.
