摘要Using the sessile drop technique, the relation between wetting and interfacial chemistry in the Zr-based bulk metallic glasses (BMGs)/W system was studied by varying the Nb content in the alloy at different temperature. The scanning electron microscopy (SEM) was used to analyze the microstructure and bonding mechanism of the Zr-based BMG/W interface. The result shows that the final contact angle of Zr-based molten alloys on W substrates increased with the increase of the Nb content in the alloy. It was found that the wetting between Zr-based BMGs and W substrate was reactive wetting in nature, and there existed the ZrW2 phase on the Zr-based BMGs/W interface. However, the interface reaction gradually disappeared with the increase of Nb content. Since Nb segregates at the interface and inhibits the reaction between W and Zr, the interfacial bonding mechanism changes from a mixing mechanism of dissolved diffusion and interfacial reaction to a separate dissolved diffusion mechanism.
