Abstract

The real structure of flame-sprayed chromium coatings in the as-sprayed state and after exposure to friction has been studied by means of electron microscopy, local x-ray spectrum analysis, and Auger electron spectroscopy. The surface layers of the coating were found to become saturated with oxygen under friction and secondary structures with a high defect content formed in those layers. The most stable structures were highly disperse fragmented states formed on the basis of the initial grains as a result of deformation.
