my country is a large electroplating country. As one of the important processing industries in my country, the vacuum electroplating industry plays a very critical role in the rapid development of the economy, society and the entire industrial system.

Since the 1950s, optical thin films have developed rapidly in two aspects: coating technology and computer-aided design. In terms of coating, a series of new ion-based technologies have been researched and applied.

The materials used in the electroplating machine are divided into two groups, namely the primer surface coating. The requirements for these two coatings are different, for example, the requirements for the primer coating

1. Vacuum coating technology is an emerging technology. It was not until the 1960s that CVD (Chemical Vapor Coating) technology was applied to cemented carbide tools.

Although there are many types of ion sources, the purpose is nothing more than online cleaning, improving the energy distribution on the surface of the PVD vacuum coating, and modulating and increasing the energy of the reaction gas.

The process of gas infiltration, diffusion, passage and overflow of the solid barrier from the denser side to the less dense side becomes permeation. The steady-state flow rate in this case is called permeability.
