Parametric investigation and optimization for CO2 laser cladding of AlFeCoCrNiCu powder on AISI 316

The purpose of the current investigation is to analyze the effect of the operating parameters of laser-assisted cladding process on clad height, clad depth, clad width and the percentage dilution in a cladding of AlFeCuCrCoNi high-entropy powder on SS-316 through CO2 laser and to optimize the claddi...
