The conditions of simultaneous mass transfer of chromium and aluminum to the surface of high-temperature alloy subjected to one-stage chromoaluminizing are determined. It is shown that the quality of such refractory coatings can be improved. The methods preventing formation of oxide inclusions in the coatings are determined. Results of comparative high-temperature strength tests of specimens after circulation and powder chromoaluminizing are presented.
