1. It is a kind of high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environment. It is made of nickel-chromium alloy with cemented carbide particles. Plasma spraying method can be used as high temperature resistance and resistance. Abrasion, oxidation and acid resistant coatings are widely used in aircraft engines and petrochemical machinery components, which can greatly increase the life of the machinery. It is also often used as a grain refiner for cemented carbide and other wear-resistant and corrosion-resistant components. Cermets based on Cr3C2 have excellent oxidation resistance at high temperatures.

Material introduction of tantalum carbide
Metal matrix composites have received extensive attention from scientists in the field of materials of various countries due to their unique advantages of high specific strength, high specific modulus, wear resistance and high temperature resistance. At present, the research on metal matrix composite materials is mainly focused on the overall uniform composite, but because the wear only occurs on the surface of the part, the overall composite is not conducive to the recovery and reuse of the material and causes pollution to the environment. On the other hand, many studies have shown that wear-resistant materials need to have both high hardness and high toughness, while the overall composite only improves the hardness, but cannot improve the toughness, while the metal-ceramic composite material maintains the high hardness and high toughness of ceramics. Excellent performance such as wear resistance, and high toughness and high ductility of the metal matrix.
