Titanium carbide powder suitable for surface strengthening treatment
Titanium carbide powder can be mixed with other carbide powders (such as tungsten carbide and vanadium carbide) to form multi-component composite powders and customize materials with different properties. For instance, after adding 10% tungsten carbide powder, the flexural strength of the sintered body can be increased by 15%, making it suitable for manufacturing parts that bear impact loads. There are various methods for preparing powders, including carbothermal reduction and vapor deposition. Among them, the powder produced by carbothermal reduction has a relatively low cost and is suitable for large-scale application. In the mold industry, molds made of multi-component composite powders are not only wear-resistant but also impact-resistant, and have a wider range of applications. 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.
