摘要：
A systematic study on the wettability and interactions between superalloy melts with various Re contents and AlO-based ceramic moulds was presented in this paper.It was found that the increase of Re content inhibited the interfacial reactions to some extent.With regard to the 0,1.5 and 3 Re alloys,a double reaction layer containing AlOand HfOwas formed at the interface,but the thickness of reaction layer decreased with the increase of Re content.However,only AlOphase was detected at the interface when the content of Re was 6 wt%,and the interface reaction was the weakest and the thickness of reaction layer was the thinnest.The wetting angle of the alloy/ceramic system increased as the level of Re increased.Moreover,the formation of viscous sand at the interface mainly depended on the change of wetting angle of the system.
