Exothermic reaction type non-metallic refractory compound composite powder

       Non-metallic refractory compounds such as BN, B4C, SiC, SiN have many excellent properties, but these materials cannot be used alone as thermal spray powder materials. Combining these non-metallic refractory compound powders with refractory transition metal Ti, Zr, Cr and other powders can produce a series of exothermic reaction type non-metallic refractory compound composite powders.



      When spraying with this composite powder, an exothermic reaction occurs between the components of the composite powder, new compounds are formed, and the porosity of the coating is significantly reduced, the bonding strength of the coating and the substrate is improved, and a high-quality wear-resistant coating is obtained. .
