The impact, wear properties of two types of materials are investigated in terms of material loss, profile of impacted and worn surfaces and variations in microstructure of surface layer and subsurface layer of the impacted end of the two types of materials. The authors study the influence of slurry properties and impact wor on the impact wear properties of the two types of materials. It is concluded that high chromiumcast iron is better than low alloy steels in impact wear properties.
