Product Detail

Product Tags

TaC coated graphite guide rings consist of a graphite substrate and a TaC coating. The surface of the guide ring is coated with a layer of tantalum carbide (TaC). The TaC coating has excellent high temperature stability, hardness and corrosion resistance, which can enhance the durability and performance of the guide ring.

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.
