Abstract

Long-term (> 10,000h) oxidation behavior of aluminide coatings made by chemical vapor deposition (CVD) or pack cementation on representative ferritic (Fe-9Cr-lMo) 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 -5,000h at 700°C. n addition, initial efforts have been made to fabricate coatings at lower aluminizing temperatures and the current results suggest that FeAI coatings can be synthesized at temperatures as low as 700°C.
