High purity tantalum carbide coated rings are annular parts with special coatings, made of high purity tantalum carbide material, which have corrosion resistance, high temperature stability, wear resistance and good thermal conductivity. They are suitable for various applications in high temperature, corrosive and wear environments, such as chemical industry, aerospace, semiconductor manufacturing and laboratory research.
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.
