    摘要:

    采用改良座滴法對Al-8Si/不銹鋼、Al-8Si/MgO和Al-8Si/TiO2體系的潤濕性和界面組織進行了研究。從熱力學(xué)角度討論了3個體系界面反應(yīng)產(chǎn)物的形成。結(jié)果表明，Al-8Si/不銹鋼的界面組織由Fe(Al,Si)3、Al7.2Fe1.8Si和Fe2Al5相組成，而Al-8Si/MgO和Al-8Si/TiO2體系的界面組織主要由不同形貌Al2O3相組成。3種體系的潤濕性測試結(jié)果表明，Al-8Si熔體在MgO上具有較好的非潤濕性能，其平衡潤濕角為124°。3種體系潤濕性的差異主要與界面產(chǎn)物的性質(zhì)和粗糙度有關(guān)。界面粗糙度測試結(jié)果表明，Al-8Si/MgO體系界面粗糙度最大，為1.46 μm，主要原因是界面反應(yīng)過程中Mg的蒸發(fā)破壞了界面反應(yīng)層的形貌，此外Ti的存在促進了Al-8Si/TiO2體系的界面反應(yīng)，增加了界面反應(yīng)層的厚度，降低了平衡潤濕角。

    Abstract:

    The wettability and interface microstructures of Al-8Si/stainless steel, Al-8Si/MgO, and Al-8Si/TiO2 systems were investigated by a modified sessile drop method. The formation of interface products of three systems was discussed from the view of thermodynamics. Results show that the interface microstructure of Al-8Si/stainless steel is composed of Fe(Al,Si)3, Al7.2Fe1.8Si and Fe2Al5 phases, while that of Al-8Si/MgO and Al-8Si/TiO2 systems consists mainly of the Al2O3 phase with different morphologies and roughness. The wettability results indicate that the Al-8Si/MgO system exhibits a better non-wettability compared with the stainless steel and TiO2 substrates, whose equilibrium wetting angle is 124°. The wettability differences of the three systems are mainly related to the roughness and properties of interface products. The interface roughness tests show that the interface of Al-8Si/MgO system has the largest roughness of 1.46 μm, which is mainly due to the evaporation of Mg that destroys the morphology of the interface reaction layer during the interface reaction process. Furthermore, the existence of Ti promotes the interface reaction and increases the thickness of interface reaction layer and thus reduces the equilibrium wetting angle of Al-8Si/TiO2 system.
