Abstract

During the study, the samples obtained by the high-speed laser cladding technology with the application of fiber lasers made by VPG Lazerone LLC were examined. This processing approach is a promising method for applying protective coatings to the metal surfaces. This article provides the coating results of 38Cr2MoAlA medium-carbon steel with the high-alloy iron-based powder materials. The resulting surface layer demonstrated the increased microhardness and wear resistance properties. The high process velocity minimized the sample heating that preserved the original geometric dimensions and minimized mixing of the deposited material with the base metal, while maintaining high adhesion between the coating and the base metal.
