Sintered titanium carbide powder of cemented carbide
Titanium carbide powder has excellent oxidation resistance. It is not prone to oxidation in the air below 600℃, and the oxidation rate at 800℃ is only 0.01mg/(cm²·h), making it suitable for manufacturing high-temperature wear-resistant components. Coating it on the surface of steam turbine blades can resist the erosion and oxidation of high-temperature gas, thereby extending the service life of the blades. The powder has a high grinding efficiency and can be used to make abrasives. When grinding hard alloys, its efficiency is twice that of alumina abrasives. In the processing of optical glass, the grinding tools made of this powder can ensure the high smoothness of the glass surface. Titanium carbide powder has excellent chemical stability. It is insoluble in common acids and bases such as water, hydrochloric acid and sulfuric acid, and only corrodes slowly in hydrofluoric acid and hot concentrated sulfuric acid. It is suitable as a raw material for making corrosion-resistant coatings. By spraying it onto the metal surface through the thermal spraying process, a wear-resistant coating with a thickness of 50-200μm can be formed, which can extend the service life of the parts by 5-10 times. The oxygen content of the powder is less than 0.1%, which can reduce the oxidation reaction during the sintering process and ensure the mechanical properties of the product. In oil drilling equipment, the coated drill bits prepared with this powder can withstand the high temperature, high pressure and corrosive environment underground.
