钎料中钯含量对氮化硅陶瓷与40CrMo钢接头组织和性能的影响
Effect of Palladium Content in Filler Alloy on Microstructure and Properties of Silicon Nitride/40CrMo Steel Brazing Joint
摘 要
采用不同钯含量的Ag-Cu-Ti-Pd活性钎料真空钎焊连接Si3N4陶瓷与40CrMo钢,对其接头组织与性能进行了研究.结果表明：钎焊过程中,钎料中的活性元素钛与钎料两侧的母材反应分别在陶瓷/钎料和钢/钎料界面形成了TiN＋Ti5Si3及Fe-Ti化合物反应层;随着钎料中钯含量(原子分数)由5%提高到20%,接头中反应层的厚度和反应产物的分布发生了变化,接头的连接强度呈现出先增大后降低的趋势.

Abstract
Si3N4 ceramic and 40CrMo steel was brazed in vacuum using AgCuTiPd active filler alloys with different Pd content.Microstructure and properties of the joint were investigated.The results show that titanium in the filler alloy react with Si3N4 ceramic and 40CrMo steel,resulting in the formation of TiN＋Ti5Si3 and Fe-Ti compound reaction layers at ceramic/filler and steel/filler interfaces,respectively.With increasing palladium content (atom content)in the filler alloy from 5% to 20 %,thickness of the reaction layer and distribution of reactants in the joint change and strength of the joint increase when the Pd content is lower than 10 and then decreased when the Pd content is higher than 10%.
