Wear resistance is brought about by the high work-hardening capabilities of these steels; this in turn is generated during the pounding ( i.e., deforming) of the surface, when a large number of disturbances are created in the lattices of their crystals that effectively block the flow of dislocations. In other words, the more pounding the steel ...

Volume wear is generally proportional to the (velocity)3. When the impact angle is small, generally less than 30°, cutting wear prevails and increasing the hardness of the surface increases its wear resistance. At high angles wear is caused primarily by deformation and impact, and a solution is rather more complex (Fig. 15).

The hardness of the material is correlated to the wear resistance of the material. If the hardness of the material is less than that of the hardness of the abrasive material, then the wear rate is high. The hardness of material plays a major role in wear resistance.
