Study on Thermal Spraying Process of Dual Hard Phase Material Cr3C2-WC-NiCoCrMo AITranslate
Abstract AITranslate
A dual hard phase material,Cr3C2-WC-NiCoCrMo thermal spraying powder,was prepared by agglomeration-sintering method,with the coating prepared by utilizing high-velocity oxygen-fuel(HVOF)spraying technology.And the effects of powder microstructure and oxygen-fuel ratio(λ)of thermal spraying on the microstructure and properties of the coating were studied.The results show that with an increase in sintering temperature,the apparent density and fluidity of the powder increase,leading to a denser microstructure.Under the condition of a fixed oxygen-fuel ratio of 1.09 during thermal spraying,the comprehensive performance of the prepared coating is relatively excellent when the sintering temperature of the spraying powder is 1295℃,with its microhardness of(1135.8±40.7)HV0.3and porosity of 1.1%±0.1%.And under the condition of a fixed sintering temperature of the spraying powder of 1295℃,the prepared coating with the oxygen-fuel ratio of 1.0 during thermal spraying has the optimal comprehensive performance,with a microhardness of(1145.8±39.6)HV0.3,a deposition efficiency of 48.8%,and a porosity of 1.0%±0.1%.
