Abstract

Abstract: It is studied that the hardened zones of 45 steel are processed through laser shock again, after laser quenched. The results indicate that properties of the zone treated through compound method is improved, compared to that through only laser quenched . The hardness increases by 15% and the wearability enhances 100%. Especially, the residual stress of the interior of the material is changed into com-pressive stress.

Key words: Residual stress, Hardness, Laser quenched, Laser shocked, Wear-resistance
