Abstract

In the present work, the behaviors of nickel and aluminum based fillers on the Ti₂AlC ceramics are studied by wetting experiments and characterization of the interface cross-section. The results show that the two kinds of fillers possess different wettability on the Ti₂AlC ceramics: the contact angle of the nickel fillers decreases continuously with rising temperature and reaches less than 20° finally, whereas that of the aluminum fillers remains larger than 135° in the full temperature range investigated. The characterization of the interface from cross-section observations reveals the presence of an interaction layer in the Ti₂AlC ceramic substrate, which promotes the wetting process.
