The paper presents the results of investigation of heat-resistant diffusion coatings on steel 08Cr7Ti and steel 45, produced by aluminizing and chromoaluminizing methods in powder mixtures at a temperature of 900–950 °C during 2–5 h. On the kinetic dependencies of oxidation of the specimens with coatings in the temperature interval of 800–l000 °C, the parametric diagrams of thermal shock resistance were plotted. They allow evaluating endurance of protective coatings at any temperatures up to 1000 °C. 8 Ref., 3 Tables, 7 Figures.
Keywords: aluminizing, chromoaluminizing, heat-resistant coatings, microstructure, phase composition, oxidation kinetics, thermal shock resistance parameter
