Laser cladding has the potential to produce corrosion or wear-resisting surfaces with a high geometrical and compositional accuracy. There is, however, little systematic data covering practical process parameters and the properties of the surfaces produced. In this study, high power CO2 and Nd:YAG laser beams have been used for cladding of plain carbon and stainless steels with various powder materials designed to be resistant to corrosion and wear. The hardness and microstructure of the clad surfaces have been studied and compared. It was found that both types of laser beam give high hardness, very homogeneous and fine microstructures, with low levels of porosity, with the absence of cracks or other defects.
