... indicated a heavily deformed surface layer with chip formation at the wear surface. The chemical composition of the liner was found to be Fe-2.74C-0.75Mn-0.55Si-0.51Ni-19.4Cr-1.15M. This alloy is highly resistant to abrasive wear, yet at the same time, prone to chipping because little plastic displacement...

.... In experiments with a steel ball on a steel flat, in which the hardness was varied from 220 to 850 HV, there was little difference in the wear loss ( Ref 46 ). In crossed-cylinder experiments with three alloys of the same crystal structure, increasing hardness is shown to lead to a decrease in the critical...
