Research on Impact–Abrasion–Corrosion Behavior of Three Typical Wear-Resistant Steels under High Impact Energy

The impact–abrasion–corrosion behavior of three typical wear-resistant steels including low-alloy wear-resistant steel, martensitic stainless steel and Hadfield steel for ball mill liner in simulated acid slurry was studied by impact–abrasion–corrosion test under high impact energy. The structure, mechanical properties and corrosion resistance of the steels have also been characterized. The result showed that the impact–abrasion–corrosion resistance of the martensitic stainless steel was the best under the condition. Further characterization revealed that the damage behavior of the three tested steels was quite different. The damage process has also been discussed by the interaction among impact, abrasion and corrosion behavior. The result is beneficial to provide reference for selection and development of impact–abrasion–corrosion resistant material for ball mill liner working in weakly acidic slurry.
