Title: The effect of complex alloying on the resistance of chromium to high-temperature salt corrosion

Abstract

The effect of lanthanum, vanadium, and silicon doping (up to 1%) on the resistance of chromium to high-temperature salt corrosion stimulated by salt-mixture melts of 75% Na{sub 2}SO{sub 4} + 25% NaCl and pure NaCl considered. It is shown that complex alloying of chromium with these metals by 0.5% each provides a high corrosion resistance to sulfide corrosion but an insufficient resistance to chloride corrosion. The resistance to the atmospheric corrosion decreases by an order of magnitude and more in the presence of salts. Acting as a depolarizer, oxygen plays a dominant role in this case.
