Abstract��The corrosive��wear performances in acidic solution and it��s mechanisms of a low carbon high alloyed steel and a high manganese steel as mill liner, were investigated through weight loss, electrochemistry and surface morphology observation. The result showed that the corrosion current density of the former was one order smaller than that of the latter. The former showed the self��passivation tendency especially after 16h in acidic solution of pH 3.5, while the latter exhibited active dissolution and weak corrosion resistance. The corrosive��wear weight losses of both steels increased with increasing impact energy. At impact energy of 2.0 J, the two steels behaved similarly, but at the impact energy of 2.7 J and 3��5 J, the former showed much better corrosive wear resistance. At 2.0 J, the failure mechanism was mainly micro��cutting for the former and was fatigue spalling of extruded hardened edge as well as corrosive wear for the latter. At 3��5 J, the main failure mechanisms were fatigue spalling of hardened edge for the former ,and was massive fatigue spalling and heavy corrosive wear for the latter. ��
