燃烧室压力对WC-10Ni5Cr涂层的组织及性能影响
Effect of Combustion Chamber Pressure on the Structures and Properties of WC-10Ni5Cr Coatings
摘要
Abstract
In this paper,WC-10Ni5Cr coatings were prepared using high-velocity oxygen-fuel spraying technology with three different spraying process parameters,and the effects of the spraying parameters on the microscopic morphology,bonding strength,porosity,deposition rate and mechanical properties of the WC-10Ni5Cr coatings were investigated.It was found that the WC-10Ni5Cr coatings prepared by supersonic flame spraying technique were well bonded with the substrate,and the bond strengths were all above 73 MPa.The coating structure is dense and the porosity is less than 0.5%.The deposition rate of the coating decreased by 10%with increasing combustion chamber pressure.The microhardness of the coating increases with increasing combustion chamber pressure,but the fracture toughness decreases.关键词
