Corrosion Behaviour of Amorphous Fe-Cr-Ni-C Alloys Synthesized by Magnetron Sputter Deposition

The results of a study of the effect of increasing carbon concentration on the crystalline-to-amorphous transition and corrosion resistance in high rate sputter-deposited 304ss-carbon alloys are reported. Charaterization using X-ray diffraction, transmission electron microscopy and auger electron microprobe analysis showed that the amorphous state was formed at carbon concentration greater than 6.2wt%.
