Abstract: In this study,Al–Ti–Cowas used to improve the surface performance of pureTi. Laser cladding is an important surface modification technique, which can be used to improve the surface performance of pureTi. Laser cladding of theAl–Ti–Co + TiB2pre-placed powders on pureTican form ceramics reinforced the composite coating, which improved the wear resistance of the substrate. Characteristics of the composite coating were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), microhardness and wear tests. And the laser-cladded coating can also have major dilution from the substrate. Due to the action of the fine grain strengthening and the phase constituent, the wear resistance and microhardness of pureTisurface were greatly improved.
