Abstract—The influence of diffusion saturation of steel 20 in the medium of low-melting liquid metal melts of Pb–Bi–Li–Ni–Cu composition on its elemental composition and corrosion resistance is considered in this article. As a result of diffusion saturation, a coating is formed structurally consisting of two zones: surface and transition ones. The surface zone contains 53% Cu, 30% Ni, and 17% Fe. As one approaches the transition zone, a decrease in the concentration of Cu and an increase in the concentration of Ni and Fe are observed. In this case, the transition zone structurally consists of inclusions of Fe in a Ni-based solid solution that did not pass into solid solution. In addition, there is a layer under the coating containing C in a higher concentration than the base material owing to the low solubility of C in solid solutions of the Cu–Ni–Fe system. The coating thickness ranges from 8 to 45 μm depending on the temperature and duration of saturation. It is also found that the resulting coatings can reduce the corrosion rate of samples from 3 to 0.8 mm/year.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
