摘要

摘要: 增加实际紧密接触面积能提高玻璃在金属表面的润湿性,文中提出了一种将可伐合金表面进行电子束毛化的方法来提高表面粗糙度. 采用座滴法研究了硼硅玻璃在毛化后可伐合金表面的润湿性. 结果表明,电子束毛化可以增大可伐合金表面的有效接触面积,促进熔融玻璃的润湿铺展,润湿角随着加热温度的升高和保温时间的延长而逐渐减小. 硼硅玻璃和氧化层之间的主要反应产物为Fe₂SiO₄,金属表面的高能束毛化和预氧化处理有效促进了玻璃-金属的机械-化学结合,有利于提高玻璃与金属的连接强度.

Abstract: The wettability of glass on metal can be enhanced by increasing the area of real intimate contact. The paper presented electron beam texturing on Kovar alloy to improve the surface micro-roughness. The wetting behavior of borosilicate glass on textured Kovar alloy was investigated by sessile drop method. The results indicated that the increase of effective contact area by using electron beam texturing facilitated the spreading of molten glass. The contact angle decreases continuously with the increase of heating temperature and holding time. The main reaction products between glass and oxide layer are Fe₂SiO₄. The high-energy beam texturing and pre-oxidation on the metal surface promoted the mechanical-chemical bonding of glass and metal effectively, which improves the connection strength of glass and metal.
