The research of surface treatment technology and coating of agricultural machinery aluminum forgings is to improve the corrosion resistance, wear resistance and appearance quality of agricultural machinery aluminum forgings, extend their service life and enhance their performance. Here are some common surface treatment techniques and coating research methods:
- Pickling treatment: Pickling is a commonly used surface treatment method, which can remove oxides, pollutants and oxide layers on the surface of aluminum forgings by using an acid solution to improve its surface quality and adhesion.
- Electroplating technology: Electroplating is the method of reducing metal ions to the surface of aluminum forgings in the electrolyte to form a metal covering layer. Common electroplating methods include chromium plating, nickel plating, etc., which can improve the corrosion resistance and oxidation resistance of aluminum forgings.
- Oxidation treatment: Oxidation treatment is the use of chemical reaction to form an oxide layer on the surface of aluminum. The common oxidation treatment methods include sulfuric acid oxidation, sulfuric acid anodizing, etc., which can increase the hardness and wear resistance of the surface of aluminum forgings.
- Cemented carbide coating: Cemented carbide coating is sprayed to the surface of aluminum forgings by spraying, thermal spraying and other methods to form a layer of wear-resistant coating. This coating can improve the wear resistance and impact resistance of aluminum forgings.
- Organic coating: Organic coating is the use of organic materials to coat aluminum forgings to form a protective film. This coating can increase the corrosion resistance and weather resistance of aluminum forgings, while also improving their appearance quality.
In addition to the above technologies and methods, there are many other surface treatment technologies and coating research methods that can be used for agricultural machinery aluminum forgings. The specific choice of technology or method should be determined according to the specific application environment and requirements, and the relevant process and performance testing.
