A better understanding of the role of composition on resisting fireside corrosion may assist in the development of improved performance or lower cost coatings. ^{13 - 15} EXPERIMENTAL PROCEDURE Abstract Using oxygen, rather than air...

...Abstract Laboratory corrosion tests were conducted to clarify the effects of addition of the alloying elements silicon and aluminum on the fireside corrosion of austenitic 20wt.% Cr -40% Ni alloy in simulated waste to energy (WTE) plants. Test results were compared with those of Mo -added alloys...
