The Reduction of the Oxidized Surface of Cobalt–Rhenium Alloys with Chromium from the Gas Phase
The development of new heat-resistant cobalt alloys for the aerospace industry allows exceeding the temperature capabilities of nickel superalloys. Cobalt alloys, however, are less resistant to high-temperature oxidation, and alloying cobalt alloys with aluminum or chromium can lead to the formation of brittle topologically dense phases. As a solution to this problem, surface alloying with the chromium of cobalt alloys, carried out by the interaction of their preoxidized surface with chromium from the gas phase, is proposed.
