Laser cladding technology has been used for erosion esistance, heat resistance and corrosion resistance. In the new solid cold spray process, the coating is formed by high-velocity particles impacting with the substrate to be coated. These particles bond mechanically with the substrate by way of plastic deformation only. Solid cold sprayed coatings have defects such as connected pores and poorly bonded lamellae which deteriorate coating properties. In this research, a direct diode laser was utilized for laser treatments of cold sprayed composite coatings. The influence of laser power and scan speed, on the properties of the laser-treated layers was investigated. The laser treatment is the present subject of research in order to obtain denser coatings with good adhesion to the substrate. Therefore laser technology in combination with solid cold spraying broadens the area of applications for cold sprayed coatings.
