摘要
Ti及Ti合金和ZrO_(2)陶瓷都因具有诸多优良的特性被广泛应用于高精尖领域,在现代工业中占有越来越重要的地位,实现Ti及Ti合金/ZrO_(2)陶瓷的可靠连接对于完成异种材料的性能互补及拓宽应用领域具有重要意义。然而,在异种材料的焊接过程中存在一些亟待解决的难题,其中主要是改善钎料在母材表面的润湿性和缓解界面应力的问题。本文着重分析了二者的连接难点,回顾了相关陶瓷和金属的钎焊研究进展,阐述了不同焊前预处理方法对接头性能的影响,最后对异种材料连接提出了展望。
Ti and Ti alloys and ZrO_(2) ceramics are extensively used in high-precision fields due to their excellent characteristics,playing an increasingly important role in modern industry.The reliable connection of Ti and Ti alloys with ZrO_(2) ceramics is crucial to complete the complementary properties of dissimilar materials and expand their range of applications.However,there are some problems to be solved in the welding process of dissimilar materials,which are mainly to improve the wettability of filler metal on the surface of base metal and to alleviate the interface stress.This paper focuses on the analysis of the connection difficulties of the two materials,reviews the research progress of brazing of related ceramics and metals,expounds the influence of different pretreatment methods on the joint performance,and finally puts forward the prospect of dissimilar material connection.
