Abstract

The Morphology and composition of surfaces and cross sections of films formed by chemical conversion and anodic oxidation on Magnesium Die Cast AZ 91D were studied by Electron Probe Microanalysis (EPMA), X-Ray Diffractometery and X-ray Photoelectron Spectroscopy. The major constituents of the chemical conversion coated film are Cr, O and Mg. It is assumed that Cr(OH)₃ is formed at the film/substrate interface and subsequently converted to microcrystalline Cr₂O₃ with film growth. The components of anodic oxide films are well-crystallized Cr₂O₃, MgF₂ and NaMgF₃. These substances occer as relatively homogeneous film.
