Trivalent chromium conversion (TCC) coating formation on AZ91D magnesium alloy has been investigated using scanning electron microscopy, energy X-ray dispersive spectroscopy (EDS), photoelectron spectroscoy (XPS). The was formed in a commercial SurTec 650 bath. XPS showed that coatings contained mainly Cr, Zr, O, S and F species, which were assigned to hydrated Cr(III) (Cr(OH)3/CrOOH), ZrO2, Cr...

Magnesium alloys, known as a “21st-century green engineering material”, are widely used in many fields, including during the production and consumption of magnesium alloys die-casting products such AZ91D, AM50, AM60B. In addition, large amount waste is generated, which not only pollutes environment but also wastes secondary resources. Hereby, we reported vacuum gasification—directional condensa...

In this work, the effects of deposited corrosion products on rates and pseudo-passivation behavior high-purity (HP) Mg AZ91D under thin electrolyte layers (TEL) in a bulk solution were investigated. Low pseudo-passive can be maintained over time TEL, especially extremely electrolytes (100 ? m 200 TEL). Pseudo-passivation HP TEL is caused by product films formed metal surface. The are composed h...

The current work aims to investigate the mechanical properties of rare oxide reinforced Mg alloy based MMCs. Magnesium matrix considered in study is AZ91D alloy, whereas earth oxides were CeO2 and Y2O3. Y2O3 particulate reinforcement percentage was varied from 1 3% steps 1% its influence on Stir casting route adopted fabricate sample for study. Microstructure analysis illustrated uniform distri...
