摘要：
The effect of Cu content on the wettability and interfacial reaction of metal supports for oxygen-permeable membranes brazed with Ag-Cu filler was investigated. The microstructure of the interface was observed by SEM and the constituent phases were analyzed by EDS. The results showed that pure Ag exhibited poor wettability on the 310S stainless steel supports; the contact angles decreased rapidly when the Cu content increased from 0 to 2% and then the contact angles decreased slowly with the increasing Cu content. The wettability of Ag-Cu/310S system in air was improved by reaction between CuO in brazes and the surface layer of 310S to form a new Cu-Cr-Fe-O oxide and to destroy the passive film from the 310S surface.
