Abstract
The present invention belongs to laser fast-molding technical field, relating to the improvement of laser melt-coated sintering molding method of the nickel substrate alloy powder. The steps of the invention comprises selecting nickel-copper-tin alloy powder as a sintering material, composing processing program and molding in sintering at the processing parameters of 1000 to 1300W laser power, 300 to 400mm/min scanning speed, 15 to 25mm defocusing amount and 15 to 25r/min powder feeding speed. The process is characterized in small alloy component segregation of the molded parts and uniform and compact organization, which solves the problems of alloy component segregation in the laser fast-molding process in the selected district and non-uniform organization.
