Effect of powdered laser surfacing modes on structure and properties of wear-resistant coating and new medium carbon steel with yield strength 1500 MPa

Abstract

This paper studies coatings obtained by laser cladding of M2 powder material (Hoganas, Belgium) on a new B1500 medium-carbon steel. The analysis of defects (pores, cracks), microstructure, phase composition, microhardness of the deposited coatings depending on heat input of laser radiation was performed. The results of tests for wear resistance of coating samples, which allow selecting the optimal modes of laser deposition, are presented.
