Experimental implementation of direct laser alloying

Abstract

A laser beam, as a source of energy, has been lately widely used in additive technologies for the manufacture of parts for the power engineering industry. One of the promising methods of additive manufacturing based on laser overlay welding of metal wires is the so-called Laser Engineering Net Shape. This work studies the structure and mechanical properties of the sample manufactured using a direct laser alloying unit designed for 07X18H10T stainless steel grade alloying. The allocation map of chemical elements has been examined in this work.
