摘要：

The influence of temperature and active element chromium to wettability of several nickel-based high temperature filler metals on three-dimension carbon fiber reinforced silicon carbide composite (3D-Cf/SiC) was studied in this paper. Additionally, the interfaces between filler metals and Cf/SiC were inspected using scanning electron microscopy (SEM), energy dispersive spectroscopic (EDS) analyses and X-ray diffractometry (XRD). It was found that the contact angle decreased with the temperature rising, also the mass fraction of element chromium has much influence on the wettability, the content of chromium increases, so the contact angle decreases. The wetting procedure is reactive wetting, and several carbides and silicides were made at interface.
