Received November 3, 2003 Abstract — Applying functional high-temperature coatings to the working surface of the blading of gas turbines is discussed. Applying the coatings by microplasma-spark alloying, with the additional ultrasound modifying, as well as, using composite electrode materials based on intermetallic compounds is suggested for the stabilization of the heat-resistant phases.
