Abstract
The effect of chromium carbide upon introducing into the charge mixture for a flux-cored wire exerted on the structure and properties of weld-deposited metal is considered. The welding deposition has been performed using a flux-cored wire in a protective gas environment. The composition of the flux-cored wires is chosen in such a way as to provide a weld-deposited metal based on the system of Cr–B–Nb–C alloyed iron. It has been shown that in the course of the welding deposition, chromium carbide decomposes, which results in alloying the weld-deposited metal with chromium and carbon and leads, in turn, to the formation of chromium carbides in the weld-deposited metal, as well as to an increase in the hardness of the deposited layer. On average, the presence of chromium carbide in the charge mixture of the flux-cored wire leads to an increase in the wear resistance of the weld-deposited metal.
期刊介绍：
Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
