The paper presents the results of investigation of heat-resistant diffusion coatings on steel 08Kh17T and steel 45, produced by aluminizing and chrome aluminizing methods in powder mixtures at 900...950 °C temperature for 2...5 h. The parametric diagrams of heat resistance were plotted on the kinetic dependencies of oxidation of the samples with coatings in 800...1000 °C temperature interval. They allow evaluating endurance of protective coatings at any temperatures up to 1000 °C. 8 Ref., 3 Tabl., 6 Fig.
Keywords: aluminizing, chrome aluminizing, heat-resistant coatings, microstructure, phase composition, oxidation kinetics, heat resistance parameter
