Process optimization of laser cladding Ni60A alloy coating in remanufacturing

•Linear energy density identifies threshold for elimination of large porosity.•A statistical model between process parameters and porosity area is developed.•Cracks are effectively eliminated with decreasing of molten pool cooling rate. The inherent problems associated with laser cladding remanufact...
