| 抄録 | The wettability of three different oriented alpha-Al2O3 single crystals, R(01(1-bar)2), A(11(2-bar)0) and C(0001), by molten Al was studied over a wide temperature range (800 C to 1,500 C) in order to determine the effect of the substrate crystallographic orientation (anisotropy). The results show that the alpha-Al2O3 substrate orientation has a significant effect on the wettability, especially at relatively low temperatures. The wettability is in the order of R greater than or equal to A greater than C(1 x 1) greater than C(square root of 31 x square root of 31)R +/- 9 deg. The dependence of the wettability on the substrate orientation is discussed according to the nature of the alpha-Al2O3 surface atomic termination structures. |
