Title: Microstructure and phase composition of Fe-based self-fluxing alloy coatings formed by laser remelting and superficially modified by laser alloying with B4C particulates
Author: E. E. FELDSHTEIN, M. A. KARDAPOLAVA, O. V. DYACHENKO
Abstract: In the present paper, the influence of laser remelting and superficial laser alloying conditions on the structure and phases of Fe-based self-fluxing alloy coatings is studied. The laser spot speed influences the changes of alloy structures and composition considerably. The presence of alloyed α-Fe and γ-Fe and a lot of hard inclusions, such as FeB and CrB, Fe3C, VC, Cr3C2 and B4C, was revealed. Laser alloying with add-in reinforced B4C particulates affects the structure and phases composition of the coating significantly.
