Abstract:
Fe-Cr-C-T-Al flux-cored wire surfacing was performed by laser, arc and hybrid methods. Laboratory tests have shown that the deposited layers vary greatly in terms of wear resistance. To identify the reasons, studies were carried out using metallographic, X-ray structural and durometric methods. The analysis of the research results showed that the reason is the difference in the cooling rates of the deposited metal in the range of 1100–800 K. This difference leads to the possibility of the formation of a metastable austenitic structure, which, in turn, affects the wear resistance of the deposited layers.
Keywords:
cored wire, wear resistance, metallography, X-ray diffraction, microhardness, laser cladding, arc deposition, hybrid deposition.
