Abstract
A chromium oxide (Cr2O3) coating was obtained on metal substrates (steel, alloy steel, etc.) by thermal decomposition of chromium acetylacetone (AA-Cr) in oxygen. The nature and quality of these coatings were investigated by a variety of analysis techniques: X ray Diffraction, Raman Spectrometry, Glow Discharge Spectrometry, Scanning Electron Microscopy and Optical Microscopy. Analysis of the influence of the substrate and precursor temperature, of the flowrate of the carrier gas (Ar) and of the reagent (O2) led to determination of the optimum coating conditions.Keywords
