Abstract Scope |
Mg alloys have high strength-to-weight ratios. However, Mg alloys easily burn and oxidize at high temperatures. To overcome the problem of flammability of Mg alloys, some reactive elements were added to Mg alloys. The reactive element oxide film formed on the Mg alloy surface may play an important role in improving incombustibility of the alloys. However, it is hard to find systematic investigation for the characterization of surface oxide film of Mg alloys in previous literatures. In this study, we have attempted to classify the oxide films of Mg-X alloys and multicomponent Mg alloys such as LPSO-typed ones. The proposed classification comprises three main types of oxides (MgO, XmOn, and XmOn/MgO) and two subgroups (thermally grown and thermal barrier) of each oxide type. The formation of thermal barrier type oxide film tends to improve non-flammability of Mg alloys regardless of sort of main oxide types. |
