Abstract

Metod of the surface modification of a sintered powder billet of the contact alloy of Cu-30%(wt.) Cr was described. The method consisted of a pulsed laser treatment of surface. As a result, on the surface of a billet the layer with cast structure characterized by a uniform fine structure was formed. The thickness of the modified layer was depended on the current of pump and speed of beam moving over the surface of the billet. Full text download
