AbstractThe corrosion behavior of Fe-19Ni-13/21Cr-xAl (x = 0, 2, 6 at.%) alloys in a carburizing-oxidizing atmosphere was compared with that in a purely carburizing atmosphere at 900 degrees C. The presence of oxygen did not improve the corrosion resistance of the two alloys Fe-19Ni-13Cr-xAl (x = 0, 2 at.%), while oxygen reduced the carbon attack significantly for the other alloys. The extent of the carbon attack decreased with the increase of the aluminum content, except for the addition of 2 at.% Al to Fe-19Ni-13Cr, which did not reduce the carbon attack. Addition of sufficient aluminum promoted the formation of external Cr2O3.; The corrosion behavior of Fe-19Ni-13/21Cr-xAl (x = 0, 2, 6 at.%) alloys in a carburizing-oxidizing atmosphere was compared with that in a purely carburizing atmosphere at 900 degrees C.
