Wetting phenomena in CuZr-based glassy alloys/W system

The wetting behavior and interfaces of CuZr-based glassy alloys/W system were investigated by the sessile drop method. It was found that Cu50Zr50/W, Cu47.5Zr47.5Al5/W and Cu40Zr44Al8Ag8/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 Cu47.5Zr47.5Al5/W and Cu40Zr44Al8Ag8/W, and some granular reaction products appeared along the interface of Cu50Zr50/W. The present work indicates that Cu47.5Zr47.5Al5 and Cu40Zr44Al8Ag8 bulk metallic glasses (BMGs) are appropriate for the fabrication of W reinforced BMGs matrix composite.
