Abstract
The present disclosure relates to a micron silver particle-reinforced 316L stainless steel matrix composite, including a 316L stainless steel matrix and silver particles uniformly distributed in the 316L stainless steel matrix. The silver particles have a weight 1% to 5% of the total weight of the composite; and the composite has a density of 7.9 g/cmto 8.2 g/cmand a relative density of more than 98%. The composite is prepared by the following method: mixing raw materials of a spherical silver powder and a spherical 316L stainless steel powder; subjecting a resulting mixture to mechanical ball milling to obtain a mixed powder; sieving the mixed powder and adding a resulting powder to a powder cylinder of an SLM forming machine; and charging an inert protective gas for printing to obtain the composite.
