Abstract

The effect of the formation of an oxide layer on the interfacial reactions between a Co-Cr-Mo alloy (CCM alloy) and molten Al is investigated. In the absence of an oxide layer, the CCM alloy reacted rapidly and an interfacial two-layer structure formed between the CCM alloy and molten Al. Upon oxidation, a uniform (Cr,M)2O3 (M: doped elements) oxide layer formed on the CCM alloy surface, which effectively inhibited the reaction between the CCM alloy matrix and molten Al for more than 2h.
