Results for stator and rotor turbine-compressor blades (EI961-grade steel) coated with (Ti, Zr)N-based corrosion-resistant coatings and tested for corrosion, wear, and fatigue are presented. Thin Zr, Cr, and Sc interlayers sandwiched between the outer coating and the base metal and treatment with a perchloric acid solution improve the resistance to corrosion. Further improvement of the corrosion-resistance properties of the blades is achieved by combining low-temperature calorizing with ion-plasma sputtering.
