Zr41．25Ti13．75Ni10Cu12．5Be22．5熔体与W的润湿及复合

Wetting and Composite Between Zr41.25Ti13.75Ni10Cu12.5Be22.5 Molten and W

摘要:

用座滴法研究了高真空下Zr41.25Tin13.75Ni10Cu12.5Be22.5（原子百分数，下同）熔体在W上的润湿行为及界面相互作用，并用浸渗法制备了W丝增强的Zr41．25Ti13．75Ni10Cu12.5Be22.5块状非晶复合材料。结果表明：在1053K～1173K之间，Zr41.25Ti13.75Ni10Cu12.5Be22.5熔体与W具有较好的润湿性。润湿温度升高会显著降低平衡接触角，并加速熔体的铺展，但也会增大W的溶解量。继续升高温度对平衡接触角和达到平衡接触角所需时间的影响很小。好的润湿性和快的铺展速率为制备W丝增强的Zr41.25Ti13.75Ni10Cu12.5Be22.5块状非晶复合材料选择合理的工艺参数提供了较大的自由空间。

Abstract:

The wetting behavior and interracial interaction of Zr41 25Ti13.75Ni10Cu12. 5Be22. 5 molten on W were studied by the sessile drop method in high vacuum. Tungsten fiber reinforced Zr41.25Ti13.75Ni10Cu12.5Be22.5 bulk metallic glass matrix composite was fabricated by infiltration process. The results show that there is a good wettability in Zr41.25Ti13 .75Ni10Cu12.5Be22. 5 molten/W wetting system between 1053 K and 1173 K. Increase of wetting temperature resulted in the decrease of equilibrium contact angle and the increase of spreading rate and solution of W. It had little effects on the equilibrium contact angle and the equilibrium wetting time when increasing above 1173 K. Good wettability and rapid spread rate provided a wide operating space for fabricating tungsten fiber reinforced Zr41.25Ti13 75Ni10Cu12.5Be22. 5 bulk metallic glass matrix composite.
