Designed fabrication of hard Cr Cr2O3Cr7C3 nanocomposite coatings for anti-wear application

Nanocrystalline CrCr2O3Cr7C3 composite coatings were fabricated by electrodeposition followed by thermal treatment. The structures of coatings were investigated using high-resolution transmission electron microscopy and X-ray diffraction analysis. The composition, elemental chemical state, mechanical properties and wear resistance of coatings were determined using energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy,...
