Abstract
The heat resistance of a 10G7M3S2AFTYu deposited steel coating was studied under conditions of a temperature of 900 °C. It was established that the main increase in the mass of scale for this steel occurs in the first hours, and later this dependence is almost straightforward. The average weight gain of the metal scale of such a coating at 900 °C is 0.0035 kg/(m2·h). It was shown that the basis of metal scale of 10G7M3S2AFTYu metal composition is Fe2O3, Fe1.26Mn0.74O3, Mn2O3, Fe3O4, as well as SiC, VO, MoO2, VNi0.81, AlC3N3, which have relatively high protective properties. The coating made of 10G7M3S2AFTYu steel can be used for applying to the surface of parts operating at temperatures not exceeding 900 ℃.
