Supersonic thermal spraying strengthening treatment on the surface of environmental protection equipment

       Environmental protection issues have always been concerned by major industries. In the process of industrial development, environmental protection is a link that government departments and enterprises pay great attention to. Therefore, the application of environmental protection equipment has gradually attracted everyone's attention. In everyone's general concept, environmental protection equipment needs to be replaced with new equipment after a period of use to ensure the environmental protection requirements of the equipment. However, the cost of replacing new equipment is relatively high. On this basis, many companies Choose to use a thermal spray process for surface strengthening.



This time, wococarbide.com was commissioned by an environmental protection company to strengthen the surface of its environmental protection equipment parts (valve body, end piece, small rotor, etc.). To strengthen the surface of environmental protection equipment parts, wococarbide.com technicians use supersonic spraying technology to spray chromium carbide coating on the surface. Chromium carbide is a gray powder with metallic luster. Its melting point is 1890℃. Therefore, it has good wear resistance, corrosion resistance and oxidation resistance under high temperature environment (1000~1100℃). It is widely used on metal surfaces. Process in the thermal spray material and cemented carbide industries.

The chromium carbide coating prepared under the supersonic spraying process has the characteristics of high hardness, wear resistance and good corrosion resistance. Compared with the tungsten carbide coating, it has better high temperature resistance and corrosion resistance. Therefore, it is used in environmental protection equipment. In the repair, chromium carbide has more advantages.
