接头的性质取决于界面形成相的性质、分布和形态.钎焊接头的力学性能有详细的文献记录,而对其电化学行为的研究却较少.因此,本研究的主要目的是了解用TiCuNi、AgCu共熔合金和Ag钎料钎焊工业纯钛接头界面处形成的相对其腐蚀行为的影响.在磷酸盐缓冲电解液中进行37℃下的开路电位和动电位极化实验,研究钛接头的电化学行为.结果表明,含Ag钎料对界面形成的富银相及钛相和工业纯钛间的微电偶腐蚀具有敏感性.然而,当使用TiCuNi钎料钎焊时,接头和母材之间没有显著差异.“,”The properties of the joints are dictated by the nature, distribution, and morphology of the phases formed at the interface. The mechanical properties of brazed joints are well documented in the literature, contrarily to their electrochemical behaviour. Thus, the main objective of this study was to understand the influence of the phases formed at the interface on the corrosion behaviour of commercially pure Ti brazed joints, produced by using TiCuNi, eutectic AgCu, and Ag filler foils. The electrochemical behaviour of the Ti joints was accessed by open circuit potential and potentiodynamic polarization tests in phosphate buffer saline solution electrolyte at body temperature. Results showed that Ag-based fillers induced susceptibility to micro-galvanic corrosion between the Ag-rich and Ti phases formed at the interface and commercially pure Ti base metal. However, no significant differences were observed between the joint system and the base material when brazing with TiCuNi filler.
