Abstract
The morphology of corrosion products formed on cobalt and nickel in argonoxygen-chlorine mixtures at 1000 K have been examined using optical microscopy, scanning electron microscopy, and X-ray diffraction. The corrosion products formed under conditions where the oxides are thermodynamically stable consist of porous oxides containing little or no chlorine. This morphology is consistent with a corrosion mechanism involving vapor phase transport of volatile metal chlorides.
