Abstract
Dry corrosion of electrochemically aluminided steels by oxygen and hyd rogen sulfide has been studied up to 1000-degrees-C. Aluminum cations were reduced on steel substrates by molten salt electrolysis at 600-de grees-C, using either constant or pulsed currents. The Fe2Al5 layer th at is always formed on the steel substrates seems to withstand dry cor rosion satisfactorily in all the different types of steel studied unde r oxygen or hydrogen sulfide atmospheres, up to 800-degrees-C.
