摘要：

In the present paper, the influence of laser remelting parameters and laser modifying with B4C, MoB and TaB particulates on the structure, phases, microhardness and wear rates of Fe-based self-fluxing alloy coatings is studied. The laser spot speed, diameter and beam overlap factor influence the changes of alloy structures and composition. The presence of alloyed alpha-Fe and gamma-Fe and a lot of hard inclusions, such as FeB, MoB, TaB and CrB, Fe3C, VC, Cr3C2 and B4C, was revealed. Laser alloying with add-in reinforced B4C, MoB and TaB particulates affects the structure and phases composition of the coating significantly. These changes affect the microhardness and wear rate of the coatings. (C) 2016 Elsevier B.V. All rights reserved.
