Wettability and interface characteristics of Ag-Cu-Ti /ZrO2system were studied by an improved sessile drop method.Wettability and interface morphology of Ag-Cu-Ti / ZrO2system were investigated in detail by ADSA( Axisymmetric drop shape analysis)-SESDROPD,X-ray diffractometer( XRD),Field emission scanning electron microscopy( FESEM) and scanning electron microscopy( SEM) with spectrometer( EDS). The results show that: the wetting of molten Ag-Cu-Ti metallic glass alloy on the ZrO2substrate belongs to the reactive wetting. With the increase in the content of Ti,the wettability of Ag-Cu-Ti / ZrO2systems are improved significantly. There is the anomalous dependence of wettability of Ag54Cu4 3Ti4/ ZrO2system on the temperatures. Ag53Cu41Ti6alloy has good wettability. With the increase of temperature,Ag54Cu43Ti4/ ZrO2and Ag53Cu41Ti6/ ZrO2interfaces reaction product TiO phase gradually thickening,Cu3Ti3O reaction layer is thinning; Ag50Cu40Ti10/ ZrO2interface,a big lump of intermetallic compound Cu3Ti3O,is easy to result in stripping of alloy and ceramic interface.
