Abstract

Topographical microstructures were fabricated on alumina by epitaxial growth of Al ₄ B ₂ O ₉ whiskers in air. The products were characterized via scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The whiskers were found to grow along the [0 0 1] crystallographic direction, and the lattice mismatch between Al ₂ O ₃ and Al ₄ B ₂ O ₉ was determined to be 0.03%. The wetting of the Al ₄ B ₂ O ₉ -whisker-coated surfaces by Ag-36.7Cu-8.0Ti at.% alloy was studied. The time needed to reach the equilibrium stage reduced as the temperature increased, and the final contact angle for liquid alloy on the rough surface was 27° at 880 °C. The wetting dynamics of the whiskers coated surfaces was investigated. After wetting, a whisker-interconnected region was formed between alumina and the alloy.
