1, modified high strength nylon alloy new material, nano β-sic powder particles have good compatibility, good dispersibility and good basic combination in polymer composites. After modification, the tensile strength of high-strength nylon alloy is increased by more than 10%, and the wear resistance is increased by more than 2.5 times.

2. The wear resistance of special engineering plastic PEEK was modified. When the amount of nano-silicon carbide treated by coupling agent is about 10%, the wear resistance of PEEK can be greatly improved.

3. Application of nano-silicon carbide in rubber tire. Adding a certain amount of nano-silicon carbide to modify the original rubber formula can improve its wear resistance by 15%-30% without reducing its original performance and quality. In addition, 20 nm silicon carbide is applied to rubber products such as rubber cots and printer fixing films, which is wear-resistant, heat-dissipating and temperature-resistant.

4. Nano-SiC composite plating nickel and other metal surfaces, using the second mixed particles of nano-particles and nickel as the matrix metal, forms an electrodeposited composite coating with high density and excellent adhesion on the metal surface, and its metal surface has the characteristics of superhard (wear resistance), wear reduction (self-lubrication) and high temperature resistance.
