In this work, the resistance behavior of various materials, including Fe-based alloys, ceramics and corresponding high apparatus of corrosion-wear in molten aluminum and its alloys, were reviewed. The synergistic effect of corrosion and wear was discussed based on corrosion and wear mechanics. The effects of dynamic agitation due to rotating of friction pairs, physical property of liquid metal and size of grain etc., on the corrosion-wear resistance performance were investigated. In addition, the characteristics of corrosion-wear resistance performance of materials in molten aluminum and its alloy were summarized. According to our recent progress referred to kinds of materials, especially a TiAl3/Ti3AlC2/Al2O3 composite, the ceramics/metal composites with a co-continuous structure will be of great advantage in the field of corrosion-wear environment of molten aluminum and its alloys.Key Words： molten aluminum; aluminum alloy; corrosion; wear; synergistic effect1 IntroductionCorrosion-wear is one of the extreme states present in engineering process. Different from corrosion-wear in aqueous media which have been found primarily based on an electro-chemical process, the corrosion-wear in molten metal involves not only the corrosion caused by the high temperature molten metal, but also the synergistic effect between corrosion and wear, which results in much greater material losses than the simple sum of losses by either process alone. It is in fact a kind of mechanical?physical?chemical process that involves dissolution, diffusion, reactions in solid and liquid, wear and interaction among them.The changes in m
