摘要：
The influences of the additions of Ti or/and Si on the wettability of Ni-base alloys on alumina were investigated with the sessile drop method. The interfacial chemical reaction products were analyzed by scanning electron microscope and microprobe. Their effects on the wettability and the affecting factors for them to be produced were discussed. A new Ni-base braze alloy (NiFeCr10Si15Ti) was designed for brazing alumina with the superior qualities such as low contact angle (less than 25 degrees), high work temperature (near 1073 K) and good resistance to oxidations, etc.
