Abstract

The results of testing corrosion resistance longevity in coatings of the Ni-M-Cr-Al-Y system at temperatures of 800, 850, and 900°C are given. The kinetic dependences of corrosion are determined, successive stages of the degradation of coatings are identified, and the effect of alloying coatings with chromium and aluminum on their degradation and durability is established.
