    By means of laser cladding process a Ti-functionally graded material (FGM) was successfully obtained based on Ti600 with preplaced powder mixtures of Ti, ceramic material and nickel based alloy powder. The wear properties of Ti-FGM presented a graded distribution. It was revealed that with a proper ratio of the mixed powder and laser cladding processing parameters, the Ti-FGM which reinforced by in situ formed TiC particles can be obtained. Light optical microscopy (LOM) and scanning electron microscopy (SEM) were used for analysis of microstructure. The results showed that, a functional graded material was successfully fabricated by laser cladding, TiC particles can be formed by in situ reaction of titanium and ceramic material. The first coating had good metallurgical bonding with the substrate. The coatings were continuous, homogeneous and crack-less with optimizing the technical parameters, and had no borderline.
