Study of Ca and Ce Additions on Different Ignition Resistance Behavior of Magnesium Alloy

Abstract:

In order to develop ignition resistant magnesium alloy, Ca and Ce elements were selected alloying elements to fabricate Mg alloy. Different content of Ce (0,0.5,0.8,1.2,1.5wt%) and Ca (0, 0.6,0.8,1.0wt%) were added into pure magnesium to analyze their ignition-proof effect. The concentration of Ce and Ca elements on the melt surface was believed to be key factor for ignition resistance, which caused the change of interfacial tensions. It was indicated that the ignition resistance could be improved with increase of Ce and Ca addition. This could be attributed to a protective surface oxide owing to the diffuse of Ce and Ca to surface.
