“…Previous studies [99][100][101][102] showed that small addition of manganese (0.2 wt.%) can increase the tolerance limit for the impurities, Fe, Cu and Ni. Nearly 70 years ago, Leontis and Rhines [42] found that Mn has no influence on the oxidation rate of pure Mg as the solid solubility of Mn in Mg is low (2.2 wt.%) [43].…”

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.

“…Chemical composition is one of the main factors. Iron, nickel and copper have extremely negative effects on the alloy's corrosion performance because their low solid-solubility limits promote the formation of intermetallic compounds in the Mg matrix [21,22]. For example, the ASTM B93 standard composition limits of AZ91D Mg-Al-Zn alloy are iron 0.005 wt%, nickel 0.002 wt% and copper 0.03 wt% [23].…”

“…The effect of impurities on Mg based materials' corrosion behaviour has thus gained great interest. Inclusions are the main issue affecting corrosion and thus have been intensively investigated in recent years [120,121], especially in conjunction with the leaching of potential toxic (Ni) elements into the surrounding causing inflammations [68,85,122,123]. The corrosion rate is reported to increase 10-100 times if the concentration of impurities rises beyond the solid solubility determined tolerance maximum [124].…”

Abstract:The future of biomaterial design will rely on temporary implant materials that degrade while tissues grow, releasing no toxic species during degradation and no residue after full regeneration of the targeted anatomic site. In this aspect, Mg and its alloys are receiving increasing attention because they allow both mechanical strength and biodegradability. Yet their use as biomedical implants is limited due to their poor corrosion resistance and the consequential mechanical integrity problems leading to corrosion assisted cracking. This review provides the reader with an overview of current biomaterials, their stringent mechanical and chemical requirements and the potential of Mg alloys to fulfil them. We provide insight into corrosion mechanisms of Mg and its alloys, the fundamentals and established models behind stress corrosion cracking and corrosion fatigue. We explain Mgs unique negative differential effect and approaches to describe it. Finally, we go into depth on corrosion improvements, reviewing literature on high purity Mg, on the effect of alloying elements and their tolerance levels, as well as research on surface treatments that allow to tune degradation kinetics. Bridging fundamentals aspects with current research activities in the field, this review intends to give a substantial overview for all interested readers; potential and current researchers and practitioners of the future not yet familiar with this promising material.
