Stellite 6 powders were deposited on low carbon steel using SLD (supersonic laser deposition) under optimized parameters. The structure, line scan of elements and porosity of coating were examined and analyzed using SEM (scanning electron microscope), OM (optical microscope) and XRD (X-ray diffraction). The adhesion strength between coating and substrate was tested by PAT-ADHESION/TENSILE and E900STM adhesive. The results showed the deposition characteristics of optimized coating with N-2 at a pressure of 3. 0 MPa, a temperature of 450 degrees C and a laser power of 1. 5 kW were compared with those of Stellite 6 coating deposited by the HVOF (high velocity oxygen fuel).
