Composite coating with ceramics balls and metal matrix for iron casting were developed in this study. Three alloys for matrix, cast iron, high Cr cast iron and Ni based self-fluxing alloy, also for ceramics balls, alumina and zirconia are tested. The erosion resistance was investigated by sand blast method. The results showed that wear weight loss of these composites coating were remarkably reduced by ceramics balls, but, it depended on metal matrix also. In its early stage, metal matrix was ground preferentially, later projecting ceramics balls resisted wear, unless the balls did not fall off. Especially partial stabilized zirconia balls have the effect of increasing the erosion resistance.
