Latest Patents

One of his latest patents is titled "Micron silver particle-reinforced 316L stainless steel matrix composite and preparation method thereof." This invention involves a composite material that includes a 316L stainless steel matrix with silver particles uniformly distributed throughout. The silver particles constitute 1% to 5% of the total weight of the composite, which has a density ranging from 7.9 g/cm³ to 8.2 g/cm³ and a relative density exceeding 98%. The preparation method involves mixing spherical silver powder with spherical 316L stainless steel powder, followed by mechanical ball milling to create a mixed powder. This powder is then processed using an SLM forming machine in an inert protective gas environment to produce the composite.

Another significant patent is for a "Coaxial powder-feeding nozzle used for additive manufacturing on inner wall and having self-cleaning function." This innovative nozzle features a partition wall-type shell, a powder flow area, a cooling liquid flow area, and a shielding gas conveying channel. It includes a powder self-cleaning filter that utilizes a suction force and the weight of residual powder to efficiently manage the flow of materials during the additive manufacturing process.
