摘要：

To　clarify　and　comprehend　the　interfacial　compatibility　of　single　crystal　superalloy　and　ceramic　core,　the　interface　reaction　of　nickel-based　single　crystal　superalloy　CMSX-4　and　silicon　oxide　ceramic　core　during　directional　solidification　is　investigated.　The　results　revealed　that　a　continuously　distributed　Al2O3　layer　is　formed　at　the　interface　of　superalloy　/　silicon　oxide　ceramic　core.　Moreover,　it　is　also　found　that　a　discontinuously　distributed　Ta/Ti　enrichment　carbide　layer,　(Ta/Ti)C,　is　formed　at　the　interface　of　Al2O3　layer/superalloy.　The　formation　mechanism　of　interface　reaction　between　the　nickel-based　single　crystal　superalloy　and　silicon　oxide　ceramic　core　is　analyzed.　©　2020　Elsevier　Ltd
