Hard coating field
Mainly for the workpiece surface hardening treatment, improve the substrate hardness, wear resistance, improve oxidation resistance, corrosion resistance and other aspects
It is mainly to improve the hardness and wear resistance of turning tools.
Glass, ceramic surface hardening and scratch resistant treatment.
Change the properties of the substrate itself, replace the new functional materials.
Improve the anti-oxidation and corrosion resistance of products for special use.
Research and development for the needs of military industry.
