The microstructure of the coating was investigated. The results show that TiC grains are preferably encircled by Cr phase. The gliding band formed in Ni crystal and the deformation twinning formed in Cr crystal are due to solidified stress. The TiC phase in interdiffusion zone dissolves more easily in Fe-matrix than in Ni-Cr phase. The microcrystals of a and y phase were also observed and their formation is related to the dispersively precipitated TiC.
