Ni-based composite coating reinforced by TiC particle was fabricated on a substrate of 16Mn steel by induction cladding of the Ni60A, Ti and C alloy powders. The growth morphology of the TiC particles and microstructure and properties of coating were investigated by SEM, X-Ray diffraction meter, transmission electron microscope and microhardness tester. The results indicate that TiC particles is synthesized in-situ, and TiC particles in-situ synthesized are fine in size of 0.5 mu m-1.0 mu m and distributed uniformly. The excellent bonding between the coating and the 16Mn steel substrate is ensured by the strong metallurgical bonding, and the coating is uniform, continuous and almost defect-free. The microstructure of induction clad coating consist of TiC particles, gamma-Ni and eutectic structure M23C6. TiC particles are formed by the stacking of the micro-octahedron TiC, which are in the shape of octahedron or petal. The petal shape TiC is composed of a great deal of micro-octahedron TiC, growing in the forms of verte-linked. The rilicrohardness of clad coating was HV9800 MPa similar to 10000 MPa.
