Abstract
The impact corrosion-abrasion characteristics of low carbon high alloy steels, high manganese steels and medium carbon steels have been investigated using different impact energies in an acid-ironstone slurry. It was shown that the mass loss from the impact corrosion-abrasion of the three steels increased with the impact energy. At the impact energy of 2.0 J, the wear resistance of the three steels was similar. At the impact energy of 3.5 J, the wear resistant to impact corrosion-abrasion of the high manganese steels and medium carbon steels was poor, but that of the low carbon high alloy steels was satisfactory. When the impact energy were increased up to 3.5 J, the mechanism was found to be changed into fatigue spalling of work-hardened layers and corrosion for low carbon high alloy steels, deep fatigue spalling and heavy corrosion for high manganese steels and deep brittle spalling and heavy corrosion for medium carbon alloy steels.
