摘要 The corrosion and impact–abrasion–corrosion behaviors of quenching–tempering Fe–Cr martensitic steels for ball mill liner were investigated in the corrosive slurry of a copper mine compared with high manganese steel. It is found that the corrosion resistance and the protectiveness of the passive film of Fe–Cr martensitic steels became worse when the carbon content increased. The quenching–tempering Fe–Cr martensitic steel showed better impact–abrasion–corrosion resistance in the corrosive slurry compared with the high manganese steel, especially the alloy steel with the carbon content of 0.3 wt.%. The synergistic effect between mechanics and corrosion has also been analyzed to further reveal the impact– abrasion–corrosion mechanism of the steels. The damage from pure mechanics accounted for the largest percentage (over 65%) for all steels, demonstrating that mechanical damage played the most important role in the impact–abrasion– corrosion behaviors of the steels. The impact and cracking resistance of the steel should also be paid special attention during the development of new materials for ball mill liner.
