Hard alloy additive - chromium carbide powder
Chromium carbide powder can be compounded with other wear-resistant material powders (such as tungsten carbide and molybdenum disulfide) to form a composite coating, which features both high wear resistance and self-lubrication, with a friction coefficient as low as 0.05. It is suitable for working conditions without lubrication or where lubrication is difficult. On the surface of the drying cylinder of papermaking machinery, this composite coating can reduce the frictional damage to the paper, prevent the paper from sticking together, and improve production efficiency. The particle size of the powder is uniform, with a particle size distribution deviation of less than 10%, which can ensure the uniformity of the microstructure of the coating and avoid performance defects. This chromium carbide powder is dark grayish black in color, with a particle size of 20-50μm. It has outstanding high-temperature stability and maintains stable performance below 800℃. By surfacing and cladding the air inlet of metallurgical blast furnaces and the surface of hot rolling mill rolls, the formed cladding layer is wear-resistant and resistant to high-temperature oxidation, which can reduce the maintenance frequency of high-temperature operation equipment and ensure continuous production.
