TaC coating is a kind of tantalum carbide (TaC) coating prepared by physical vapor deposition technology, it has the following characteristics:

1. High hardness: TaC coating hardness is high, usually can reach 2500-3000HV, is an excellent hard coating.

2. Wear resistance: TaC coating is very wear-resistant, which can effectively reduce the wear and damage of mechanical parts during use.

3. Good high temperature resistance: TaC coating can also maintain its excellent performance under high temperature environment.

4. Good chemical stability: TaC coating has good chemical stability and can resist many chemical reactions, such as acids and bases.
