Characterisation of fresh surface oxidation films formed on pure molten magnesium in different atmospheres

This paper examines the early stages of surface oxidation of liquid magnesium under argon, air, and air mixed with protective fluorine-bearing gases. Surface film characteristics such as morphology, thickness and composition are determined.

Influence of cerium addition on the resistance to oxidation of AM50 alloy prepared by rapid solidification

The influence of various cerium (Ce) additions and starting temperature on the resistance to oxidation of AM50 alloy prepared by rapid solidification (RS, RS-AM50 alloy) has been investigated. The Ce addition has two opposite effects on the oxide scale.

High temperature oxidation of AZ91D magnesium alloy granule during in-situ melting

? Rising oxide/metal ratio during in-situ heating prevents melting AZ91D granule. ? Heating time affects oxide formation more than heating temperature does. ? Oxide grows linearly at 650?750?C and the growth enhances remarkably beyond 750?C. ?

Interactive effect of cerium and aluminum on the ignition point and the oxidation resistance of magnesium alloy

This paper focused on the interactive effect of cerium (Ce) addition and aluminum (Al) content in magnesium alloy on ignition point and oxidation resistance. Ce content played an important role in improving the oxidation resistance of Mg alloy. Ignition point ascended with increasing Ce content. 0.
