Abstract

The samples with titanium implanted on aluminum foil surface (Ti/Al) treated in air at different temperatures (25-500°C) have been studied using atomic force microscopy (AFM), X-ray diffraction, sclerometry, low temperature krypton adsorption. The AFM method data reveal that titanium implantation leads to formation of secondary porous structure, accompanied by a simultaneous increase in the surface area (from 0.004 up to 0.3 m2/g) and mechanical strength of surface layer (from 1.5 up to 3.3 GPa) in comparison with initial aluminum foil. Maximum values of specific surface area (1.3 m2/g) and mechanical strength of surface layer (5.2 GPa) are obtained after treatment of implant at 400 °C, which is associated with the formation of a larger number of mesopores in the surface layer. The prospect of using such a sample as catalysts support is shown.

注入钛后铝箔的表面形貌
采用原子力显微镜(AFM)、x射线衍射、硬结学、低温氪吸附等方法研究了在不同温度(25 ~ 500℃)空气中处理的铝箔表面注入钛的样品(Ti/Al)。AFM方法数据表明,与初始铝箔相比,钛的注入导致了二次多孔结构的形成,同时使表层的表面积(从0.004增加到0.3 m2/g)和机械强度(从1.5增加到3.3 GPa)增加。植入物在400℃处理后获得了最大的比表面积(1.3 m2/g)和表层机械强度(5.2 GPa),这与在表层形成更多的介孔有关。展望了该样品作为催化剂载体的应用前景。
