Title: Evaluation of Iron Aluminide Coatings for Oxidation Protection in Water Vapor Environment

Abstract

Long-term (> 10,000h) oxidation behavior of aluminide coatings made by chemical vapor deposition (CVD) or pack cementation on representative ferritic (Fe-9Cr-1Mo) and austenitic (type 304L stainless steel) are being studied in air + 10% water vapor in the temperature range of 650-800 C. Unlike the uncoated alloys, which are severely attacked in this environment, the CVD aluminide coatings have not failed after 16,000h at 700 C or 10,000h at 800 C. The pack aluminide coatings also show good oxidation protection after testing for {approx}5,000h at 700 C. In addition, initial efforts have been made to fabricate coatings at lower aluminizing temperatures and the current results suggest that FeAl coatings can be synthesized at temperatures as low as 700 C.
