Abstract
Morphology of surface, element and phase composition of the Al₂O₃ + Cr + TiN composite coatings deposited by the combined methods using the pulse-plasma and vacuum-arc technologies with subsequent electron beam treatment were examined by scanning electron microscopy with microanalysis, back-scattered protons and X-ray diffraction analysis. It is shown that exposure to the high-power flow of electrons causes a change in structure, composition and properties of the composite coatings.
 
 
Keywords: composite coating, pulse-plasma, vacuum-arc and electron beam treatment, electron exposure, structure and phase composition, X-ray diffraction analysis, surface modification
