Characteristics of surface layer structure formation during laser boriding
Abstract
The surface layers of a mild steel and steels 40 and U8 were studied metallographically following a laser boriding treatment. In particular, the structure and properties of the borided layer were investigated as a function of the irradiation rate and the thickness of the coating compound. It is shown that laser boriding produces a sharp increase in the hardness of the steels and leads to the formation of hardened layers that are as thick as those produced by diffusion boriding treatments.
