%X The impact corrosion and abrasion behavior of three steels used as the liner of wet-grinders in acidic-ironstone slurry and at an impact energy of 2.7 J was investigated using a modified impact corrosive test rig. The worn surface morphologies of the steels were observed using a scanning electron microscope, while the worn subsurface cross-sections of the steels after impact corrosive abrasion in the acidic-ironstone slurry for 8 h were analyzed using an optical microscope. It was found that the low carbon high-alloyed steel had much better impact corrosion and abrasion properties than the high manganese steel and medium carbon alloyed steel, which was ascribed to the differences in the compositions and microstructures of the three steels. Moreover, the low carbon high alloy steel was mainly characterized by spalling of extruded hardened edge, slight corrosive wear, and slight fatigue spalling during the impact corrosive abrasion process. Different from the low carbon high alloy steel, the high manganese steel was dominated by deeper fatigue spalling and heavy corrosive wear under the same testing conditions, while the medium carbon alloyed steel was characterized by deep brittle spalling and heavy corrosive wear.
