摘要: Abstract In this investigation, nickel (Ni)-coated WC-12Co powder was produced using an electroless nickel‑phosphorus (Ni-P) plating process and then used as a feedstock material for laser cladding of AISI 321 stainless steel substrate. The correlations that exist between key operational parameters the (i.e., power, scanning speed, feeding rate) geometrical characteristics single claddings (i.e. height, width, dilution, wetting angle) were predicted analyzed by regression analysis method (RA). A processing window Ni-coated on developed based empirical-statistical model compared with commercial without coating. Furthermore, influence microstructure microhardness investigated those cladded claddings. results showed use could significantly reduce porosity percentage lead to high-quality
