Heat Treatment Technology And Vacuum Coating Technology Are Converging
Jan 24, 2023| Heat treatment technology and vacuum coating technology are converging
● The current state of convergence
With the development of high and new technology, a single material surface modification technology can not meet the needs of the development of high-end products. In many ways, in recent years, the two technologies have been converging, penetrating and reinforcing each other.
Fusion One: Heat treatment technology assisted vacuum coating technology
A low-temperature nitriding process is performed between the heavy-duty die surface and the hard coating to add a bearing layer.
Low-temperature nitriding and carburizing on the stainless steel surface improved the hardness of the stainless steel while maintaining corrosion resistance and a beautiful decorative effect.
Fusion two: vacuum coating technology assisted heat treatment technology
A CrN and WC transition layer was deposited by magnetron sputtering on the surface of low-temperature tempered wear-resistant parts, and then DLC was deposited by PECVD to add a self-lubricating coating with high hardness and low friction coefficient.
High-density nitrogen ions obtained by arc discharge can be used to improve nitriding speed.
More energetic electron streams fired from hot filaments to enhance glow discharge and nitrogen ion density and nitriding speed;
The theory of plasma physics guides the use of active screens in ion nitriding to better play the role of active screens.
