Intensive laser repair through additive manufacturing of high-strength martensitic stainless steel powders (I) –powder preparation, laser cladding and microstructures and properties of laser-cladded metals

The intensive high-strength martensitic stainless steel (IHMSS) was designed and prepared. Influences of various parameters of electrode-induced gas atomization (EIGA) on qualities of IHMSS powders were investigated through the orthogonal test design. The IHMSS powders prepared through the optimized...
