The direct laser deposition of metal powders is one additive method of producing functional materials. It consists of the melting of metallic powders by a laser beam in inert gas. The main process parameters are the laser-beam power, laser-beam speed and scanning trajectory, and powder consumption. Each parameter is selected depending on the alloy type, which in totality affects the structure and...
316L stainless steel powder was used for volumetric laser cladding. We studied the microstructure of obtained objects, diffusion processes of the substrate components and the metal of laser cladding. Various strategies of layering metal powder were offered and mechanical tests of the samples properties were performed.
