The porous tantalum carbide coated barrel has excellent heat resistance, corrosion resistance and mechanical strength, which enables it to maintain stable performance when operating in high temperature, corrosive environment and harsh conditions. It also has excellent catalytic activity and selectivity, and can be used in chemical processes such as catalytic reaction, catalytic hydrogenation, and catalytic cracking.
In addition, the porous tantalum carbide coated barrel also has good adsorption properties and can be used in applications such as gas adsorption, separation and storage. Its porous structure can achieve efficient gas separation and storage, such as gas storage materials, separation membranes, etc.
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.
