A hard coating machine is a specialized piece of equipment used to deposit hard coatings on substrate surfaces. Its core function is to form high-hardness, wear-resistant, and corrosion-resistant functional films using technologies such as physical vapor deposition (PVD) or chemical vapor deposition (CVD) to extend the service life and performance limits of the substrate material. The following are its technical principles and core advantages:

Hard coating machines deposit metal-based, ceramic-based, or composite coatings on substrate surfaces using PVD or CVD technology. Its core advantages include:

1. High hardness and wear resistance: The microhardness of the coating typically exceeds 2000 HV, significantly reducing wear on tools or parts and extending their service life.

2. Corrosion resistance: The coating effectively isolates the substrate from corrosive media, making it suitable for harsh environments such as chemical and marine environments.

3. Low coefficient of friction: The coefficient of friction can be as low as below 0.3, reducing energy loss and improving equipment operating efficiency.

4. Thermal stability: Some coatings maintain stable performance at high temperatures, making them suitable for high-speed cutting or aerospace applications.

5. Environmental friendliness: PVD/CVD processes produce no waste, meeting clean production requirements.
