REVIEW OF THE WEAR AND GALLING …
Hardness–In general, resistance to wear is increased by increasing hardness, provided other factors remain constant. There is some question, however, whether the controlling hardness is the bulk hardness or simply surface hardness. It has been stated that to increase wear resistance, hardness should be increased by alloying or heat treatment.
