Effect of overlap technique on hardness and fatigue behavior in ND-Glass laser heat treatment of carbon steel

Abstract

The engineer faced a state where it is desirable that the component should have a surface properties differing from those of its interior, therefore core with high strength and sufficient toughness, to take up the mechanical forces combined with high surface hardness to combat wear are needed. This requirement cannot be satisfied by one material (1,2). The direction is turned to surface treatment as the only means of achieving this ends.
