Abstract
A low carbon steel plate was treated by surface mechanical attrition (SMA) and its surface layer structure was analyzed by using XRD and TEM. The results reveal that the surface layer has transformed into nanocrystalline structure. Its friction and wear behaviors have been studied compared with the untreated sample on a reciprocating friction tester. The results show that the friction coefficient of the treated specimen is markedly decreased, and its wear volume loss is reduced under the low loads and middle loads. The SEM observation of the wear scars shows that the nanocrystalline layer may reduce the effect of fatigue wear. So the friction and wear properties of the low carbon steel can be improved by means of surface nanocrystallization.
