“…Recently, Lin et al [143] found a 50 C increase in the ignition temperatures of both AZ91 and AM50 alloyed with 0.25 wt.% Ce due to the formation of a compact Ce2O3 layer that has the P-B ratio of 1.16. When mixed with MgO, the combined oxide film was regarded as dense with few defects [143].…”

Highlights The oxidation behaviours of Mg alloys from low to high temperatures are reviewed. Characteristics of MgO during oxidation is discussed. Mechanisms of Mg oxidation is presented. Effect of various alloying elements is analysed. AbstractThis paper reviews (i) the oxidation of Mg alloys at elevated temperatures in air; (ii) the influence of alloying elements on the oxidation of Mg alloys; and (iii) the progress in the development of oxidation-resistant Mg alloys. Low oxidation rates have been shown by Mg alloys containing the alloying elements, Ca, Be and rare earth elements. However, these alloying elements may also decrease mechanical properties, such as ductility.

“…Another possible reason is potential oxidization of the thin film surface. Although Mg is very sensitive to oxidization, 53 our sample was transferred in ambient atmosphere from the deposition chamber to the reaction chamber. Thus, the surface with a very thin ͑and can be discontinuous͒ Pd capping layer is likely to be partially or fully oxidized.…”

Positron depth profiling of the structural and electronic structure transformations of hydrogenated Mg-based thin films J. Appl. Phys. 105, 043514 (2009) We have developed an infrared imaging setup enabling in situ infrared images to be acquired, and expanded on capabilities of an infrared imaging as a high-throughput screening technique, determination of a critical thickness of a Pd capping layer which significantly blocks infrared emission from below, enhancement of sensitivity to hydrogenation and dehydrogenation by normalizing raw infrared intensity of a Mg thin film to an inert reference, rapid and systematic screening of hydrogenation and dehydrogenation properties of a Mg-Ni composition spread covered by a thickness gradient Pd capping layer, and detection of formation of a Mg 2 Si phase in a Mg thin film on a thermally oxidized Si substrate during annealing.

“…Liang et al [11] chose silicate and phosphate electrolytes to improve the corrosion resistance of magnesium alloy. Additives were used to improve corrosion resistance of the coatings [12][13][14]. The corrosion resistance was improved greatly; however, MAO coatings still exhibited poor corrosion resistance [15].…”

Abstract:The ultrasonic micro-arc oxidation (UMAO) was used to fabricate ceramic coatings on magnesium alloy. UMAO coatings were produced at 60 W input ultrasonic. The effects of the ultrasound on the microstructure, phase composition, elemental distribution and corrosion resistance of the coatings were extensively investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray spectrometry (EDX) and electrochemical workstation. The results showed that ultrasound improved the homogeneous distribution of micro-porous structure. The coatings were mainly composed of MgO ceramic and small amount of calcium and phosphorus with porous structure. The Ca/P ratio of the coatings increased when 60 W ultrasonic was used. The corrosion potential in simulated body fluid (SBF) changed from 1.583 V of bare magnesium alloy to 0.353 V of magnesium alloy coated under 60 W ultrasonic. The corrosion resistance of UMAO coatings was better than that of MAO coatings.
