The interaction of alumosilicide coating on steel 20 with melted eutec
tics of lithium, sodium, and potassium carbonates (4:3:3) was investig
ated in CO2 atmosphere either under anodic polarization at 600 or 800
degrees C and without polarization at 600 degrees C. The coating struc
ture, thickness, and content of aluminum were determined depending on
the test conditions. Iron dissolution was measured by chemical analysi
s.
