The erosion resistance properties of O’-Sialon-BN in molten steel are investigated in this work. According to experimental results and theoretical analysis, BN in O’Sialon-BN plays an important role in molten steel erosion resistance. And the erosion kinetics of the O’-Sialon-BN composites in molten steel is controlled by two stages: the first one is controlled by chemical reaction taking place on the interface;the second one is controlled by diffusion. The erosion surface of the materials is also investigated with fractal theory. The results show that the fractal dimensions of the erosion surface vary with erosion time from a linear way to parabolic way, which relates to the change of erosion mechanism from interface chemical reaction to diffusion.
