Tantalum carbide coating provides excellent mechanical strength and corrosion resistance, effectively protects the porous graphite matrix, and prolongs the service life of the material. Secondly, the porous graphite matrix has a highly porous structure, a large specific surface area and excellent adsorption performance, and can be widely used in catalysis, adsorption and mass transfer.
In addition, tantalum carbide coated porous graphite materials also have good thermal conductivity and stable electrochemical properties, which can be used in thermal management, batteries and electrochemical energy storage devices to improve product performance and cycle stability.
Tantalum carbide coated porous graphite materials have the potential for wide application in many fields. In the field of catalysis, it can be used as an efficient catalyst support material, providing a larger reaction interface and better catalytic performance, and promoting chemical reactions. In the field of environmental protection and energy, it can be used in wastewater treatment, gas adsorption and energy storage, etc., to contribute to solving environmental problems and promoting sustainable development.
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.
