Abstract
Multicomponent coatings on ZhS26 oxidationresistant nickel alloys produced by liquidphase activated diffusion process and selfpropagating hightemperature synthesis are studied to protect turbine engine blades against hightemperature gas corrosion Thermodynamic analysis of potential reactions in conditions of diffusion coating and chromium plating in a multicomponent mixture is carried out Results of Xray diffraction and hightemperature corrosion resistance of the coatings at 1200°C are presented The coatings are corrosionresistant and selfhealing Their oxidation resistance is much higher than that of the uncoated alloy
