even wear
8.Study shows that work hardening cannot improve the wear properties of samples significantly under the conditions of impact abrasive wear by using the abrasive ofquartz and two-body abrasive wear in which corundum is the main abrasive, but it can improve the wear properties of samples remarkably, even twice as that of the original wear property at the suitable peening time, after surface nanocrystallization in the conditions of two-body abrasive wear and three-body abrasive wear by using the abrasive of glass.
