Abstract

The paper reports the results of studying the phase compositions of the metallic compounds that participate in the aluminum and chromium transfer from powders on the metal surface upon vacuum chromoaluminizing and the life characteristics of combined condensation-diffusion coatings containing Cr, Al, Ta, W, Hf, and Y. The presence of high-temperature metals in the sublayer of aluminide coatings is found to increase the life of the parts operating at temperatures up to 1100–1150°C substantially.
