Summary: | Multicomponent coatings on ZhS26 oxidation-resistant nickel alloys produced by liquid-phase activated diffusion process and self-propagating high-temperature synthesis are studied to protect turbine engine blades against high-temperature gas corrosion. Thermodynamic analysis of potential reactions in conditions of diffusion coating and chromium plating in a multicomponent mixture is carried out. Results of X-ray diffraction and high-temperature corrosion resistance of the coatings at 1200°C are presented. The coatings are corrosion-resistant and self-healing. Their oxidation resistance is much higher than that of the uncoated alloy. |
