Studies and Research on the Hardening of Some Industrial Benchmarks Through Laser Cladding

Abstract

Industrial benchmarks are often subject to the wear and corrosion of the working environment. Laser cladding is a surface modification process that can improve their lifespan by ensuring hard, homogeneous, non-porous layers. The paper presents a series of experiments aimed at testing and calibrating the injection system used, making laser cladding with Ni-Cr-B-Fe-Al alloy on a series of industrial benchmarks and characterizing them in terms of hardness, thickness and microstructure.
