摘要：
Al/Mg powders were used to improve the wear resistance of pure Ti, which owns a great potential in the field of the surface modification. Synthesis of a hard composite coating on pure Ti by laser alloying of All Mg+TiN/TiC+Y2O3 pre-placed powders has been investigated in detail. SEM image indicates that a composite coating with metallurgical joint to the substrate is formed. The XRD result indicates that such composite coating mainly consists of Ti3Al, Al12Mg17, TiC0.3N0.7, TiN and TiC. Compared with pure Ti substrate, an improvement of wear resistance is observed for such coating.
