AbstractEffect of C on wettability and interface reaction between a nickel based superalloy and ceramic material was investigated by using a sessile drop method. It was found that the content of C in the alloy is able to influence the wettability and interface reaction. Alloys with C content lower than 0.1wt.% are stable on ceramic material and no interface reaction generates at the alloy-ceramic interface. However, when C content is higher than 0.1wt.%, the interface reaction occurs and the wetting angle decreases quickly. The product of interface reaction is discontinuous and composed of 9Al(2)O(3)center dot Cr2O3. Such result indicates that Cr in the alloy is impossible to react with the ceramic material and form Cr2O3 without the assistance of C. It is suggested that C in the alloy deoxidizes SiO2 in the ceramic material and produces SiO and CO. SiO is unstable and it can release active O atom at the interface. Cr at the interface combines with free O atom and forms Cr2O3 center dot Al2O3 in the ceramic material and Cr2O3 finally forms 9Al(2)O(3)center dot Cr2O3.
