Wear resistant and oxidation resistant SIC coating
The wear-resistant and oxidation-resistant SIC coating is a kind of high-performance wear-resistant and oxidation-resistant material, which is composed of high-performance silicon carbide and graphite surface by CVD. It is widely used in high performance materials for erosion, cavitation and high temperature. It is also used to prepare wear-resistant and anti-corrosion coating on the surface of machine parts with wear-resistant and anti-corrosion requirements.
Main features:
1. High temperature oxidation resistance: oxidation resistance, when the temperature is up to 1600 ℃, the oxidation resistance is still very good;
2. High purity: prepared by chemical vapor deposition under high temperature chlorination condition;
3. Erosion resistance: high hardness, dense surface and fine particles;
4. Corrosion resistance: resistant to acid, alkali, salt and organic reagent;
5. SiC surface layer is β - SiC, which belongs to face centered cubic.
