Abstract

In recent years, combination methods for surface hardening of alloys have been actively developed and incorporated into industrial practice. The widespread interest in such technologies is explained by the possibility of obtaining extremely high-quality surface properties for the pieces. In this paper, we consider the technology for combination surface hardening of low-carbon steel, involving laser alloying of the surface with nitride forming elements followed by nitrïding of the entire alloyed layer. We have investigated the properties of the hardened surface layer.
