Abstract
The corrosion behavior of Alloy 214 and the intermetallics Fe3Al, TiAl and MoSi2 was investigated in dry air and air with 2% Cl-2 at temperatures of 3 00 to 800 degrees C. The results show that corrosion resistance of Alloy 21 4 and the two aluminides very much depend on the test temperature. For TiAl massive corrosion starts at 500 degrees C. Alloy 214 shows corrosion rates similar to chromia formers at temperatures of 650 and 800 degrees C while the best corrosion resistance of all alumina formers tested is revealed by Fe,AI. For MoSi2 only some little ("internal") oxidation is observed even a t 800 degrees C.
