Abstract
The wetting behavior and interfaces of CuZr-based glassy alloys/W system were investigated by the sessile drop method. It was found that Cu 50Zr 50/W, Cu 47.5Zr 47.5Al 5/W and Cu 40Zr 44Al 8Ag 8/W system had the final equilibrium contact angle around 18°, 8° and 3° at corresponding experimental temperatures. Base on the scanning electron microscopy observing, no reaction product can be found at the interface of Cu 47.5Zr 47.5Al 5/W and Cu 40Zr 44Al 8Ag 8/W, and some granular reaction products appeared along the interface of Cu 50Zr 50/W. The present work indicates that Cu 47.5Zr 47.5Al 5 and Cu 40Zr 44Al 8Ag 8 bulk metallic glasses (BMGs) are appropriate for the fabrication of W reinforced BMGs matrix composite.
