C/SiC陶瓷基复合材料与铌合金钎焊机理研究
Study on brazing mechanism of C/SiC ceramic matrix composite to Nb alloy
摘要
Abstract
The active brazing method of C/SiC ceramic matrix composite to Nb alloy is discussed.The wettability of Ti-and Cu-based brazing alloys respective on C/SiC ceramic matrix composite and Nb alloy is studied,and the diffusion features of microcosmic elements on brazing connection interfaces of the two brazing alloys are investigated by the aid of scanning electron microscope(SEM) and metallographic phase analysis.The research results show that the active brazing mechanism of ceramic matrix composites to Nb alloy is that the active elements in brazing alloys are diffused to ceramics and Nb alloy respectively and chemically reacted with each other to realize the perfect bonding among them.关键词
