Microstructure and Wear Properties of Laser Coating Reinforced by Ti(CxN1-x on Adamite Roller

Fe-based layer with Ti(CINI-x) particulates on Adamite roller surface was obtained by a 5 kW traverse-flowing CO2 laser cladding technology. The microstructures of the layer were detected by optical microscopy (OM), X-ray diffraction (XRD), scanning electron microscopy (SEM), and electron probe microscopy analysis (EMPA). The tests of wear resistance was carried out on the test machine. It was seen that a good metallurgical bonding between the coating and the substrate was achieved. The microstructure contains bulky dendritic crystal and small size Ti(CINI-x) grains that are uniformly distributed in the solid solution matrix. The wear tests showed that the laser coating provided an excellent wear resistance property at room temperature.
