Abstract
Morphology of an aluminized and chromoaluminized steel surface was inv estigated before and after its interaction with carbonate melt Li2CO3- K2CO3 at 650 degrees C-under a CO2 + 0.5O(2) atmosphere for 20-1000 h. The phase composition of the coating, its variation with layer thickn ess, and the depth distribution of the coating and substrate component s were determined. Local corrosion of the coating during its depositio n and insignificant diffusion of aluminum in the steel surface under t he coating were reported.
