The
impact corrosion and abrasion behavior of three steels for liner were investigated under different
impact energy in ironstone
slurry. The results show that their weight loss increases with increasing
impact energy and approximate weight loss is observed for the three steels at impact energy of 2.0J. At impact energy of 2.7 J and 3.5 J, the wear resistance of low carbon high alloy steel (LCHA) is the best. The failure mechanism depends on the materials and impact energy.At impact energy of 2.0 J,micro-cutting for LCHA, fatigue spalling of extruded hardened edge and corrosive wear for high manganese steel(HMN),small brittle spalling and corrosive wear for medium carbon alloy steel (MCA) are responsible for impact wear failure,respectived. At impact energy of 2.7 J, it is mainly spalling of extruded hardened edge for LCHA, primarily massive fatigue spalling and heavy corrosive wear for HMN and principally massive brittle spalling and heavier corrosive wear for MCA. At impact energy of 3.5 J, it is mainly fatigue spalling of work-hardened layer and corrosive wear for LCHA, primarily large fatigue spalling and heavy corrosive wear for HMN and large brittle spalling and heavy corrosive wear for MCA.
