摘要：ZrB2 has been attracted much attention for structural materials applications due to their unique combination of relative lower density, high melting point, high hardness, strong corrosion resistance, excellent thermal conductivity, good electrical conductivity and so on. However, the preparation of zirconium boride coating is difficult to realize. In this paper, zirconium boride was coated on the surface of the silicon carbide substrate by chemical vapour deposition (CVD). When the molar ratio of ZrCl4 to NaBH4 was 1:8, zirconium boride deposition layer was the densest. And the preparation methods, composition and microstructure of coating were investigated.
