Analysis from three aspects, 2023 common metal surface treatment technology and processability.

In modern manufacturing, metal surface treatment technology is an indispensable part. It can not only improve the corrosion resistance, wear resistance and aesthetics of the material, but also improve the performance of the material and extend the service life. In 2023, there are many common metal surface treatment technologies that will continue to be widely used in various industries. This article will analyze these technologies in detail from the perspective of materials and processes to help readers better understand and apply them to actual production.

Technology for improving the hardness of metal surface

1.quenching process: 

by heating the metal to the critical temperature after rapid cooling, so that the metal grain refinement, thereby improving the hardness and strength.

2. Ion carburizing process: 

ion carburizing is carried out while heating the metal surface, so that carbon atoms penetrate into the metal lattice to form a high carbon layer, thereby improving the hardness.

3. Nitriding process: 

The metal is placed in an environment containing ammonia gas, and nitrogen is infiltrated into the metal surface through heat treatment to form a nitriding layer to improve hardness and wear resistance.

Second, improve the corrosion resistance of metal surface technology

1. Coating technology: 

including electroplating, hot dip plating, electroless plating and other ways, through the formation of a protective covering layer on the metal surface to prevent the metal from contacting with the external environment, to achieve the purpose of corrosion resistance.

2. Anti-oxidation treatment: 

the metal surface is heated to a certain temperature and quickly cooled to form an oxide layer, which has good oxidation resistance and can effectively prevent the oxidation of the metal surface.

Third, the technology of improving the beauty of the metal surface

1. Polishing process: 

by means of mechanical friction or chemical solution, remove the defects and inhomogeneity of the metal surface, greatly improve the surface finish, and obtain reflective effect.

2. Spraying process: 

the pigment or coating is sprayed on the metal surface to form a uniform coating, which can not only beautify the metal surface, but also play a protective role and improve corrosion resistance.

3. Laser treatment: 

The use of laser beam to etch and melt the metal can form a variety of textures and patterns, giving the metal surface a unique beauty.

In summary, the common metal surface treatment technology in 2023 covers aspects such as hardness enhancement, corrosion resistance and aesthetic improvement, which can meet the quality requirements of metal materials in different industries. As a member of the manufacturing industry, we should pay close attention to the development and application of these technologies to improve the competitiveness of products and market share.
