Документ Study of physical and mechanical properties of diffusion layers obtained using composite saturative environments(Національний технічний університет "Харківський політехнічний інститут", 2019) Kruglyak, Irina Vasil‘evnaMulticomponent diffusion saturation can increase the hardness and wear resistance, heat resistance and corrosion resistance of metals and alloys in various environments, due to the formation of phases of a complex composition and structure in the surface layer. The physicomechanical properties of diffusion layers obtained using composite saturating media are investigated. Surface saturation of alloys simultaneously with two elements has an advantage over saturation with one element. It allows you to combine in the resulting coating the properties created by individual elements with the special properties of their compounds. Due to the fact that the elements that make up the saturating mixture have different diffusion coefficients in the alloy, and also have a mutual influence on the diffusion rate of each other, the choice of the composition of the charge in a complex process is a difficult task. Оn the results, we can say mechanical stresses (in this case, the compressive residual stresses) affect the corrosion behavior of metals, due to the extraction of the structural material by the fact that the level of residual stresses in coatings obtained under composite saturating environments charge is higher. As a result, the probability of micro-bursting of passive oxide skins is reduced, resulting in an increase in corrosion resistance.
