| titleOfInvention | Gradient cermet coating prepared by selective laser sintering and preparation method |
| abstract | The invention discloses a gradient metal-ceramic coating prepared by selective laser sintering and a preparation method. The gradient metal-ceramic coating is composed of a primer layer, a transition layer and an outer layer; the primer layer is a high corrosion-resistant nickel-based high-resistant Corrosion alloy metal layer, its composition is: Co 21.3%, Cr 25.6%, Mo 12.5%, Nb 6.7%, the balance is Ni; the outer layer is a ceramic layer, and its composition is: C 12.5-18.7%, N 19.7 -23.4%, B 15.8%, Re 2.7%, and the rest is Si; the transition layer is a metal-ceramic composite layer; the sintering method of the coating adopts the selective laser sintering technology. In the present invention, the selective laser sintering technology is used to form a ceramic-metal composite coating with metallurgical bonding and basic continuous changes in physical and mechanical properties, so as to avoid the falling off of the ceramic layer caused by the concentration of interlayer stress, and effectively improve the high temperature resistance, high temperature resistance and high temperature resistance of the ceramic coating. Anti-oxidation and anti-corrosion ability, suitable for large-scale production. |
