An open microchannel was produced by a powder-metallurgical microchanneling process using Al as a body metal and Zn as a sacrificial-core metal. However, the cross-sectional area of the microchannel was larger than that of the sacrificial core; it increased as the compacting pressure increased. The nanoporous alumina film was produced by anodic oxidation of the inner wall of the microchannel.日本実験力学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/74640https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/74640/1/J.JSEM%2011.%20s267.pdf1346-49301346-4930AA11822914実験力学11Special Issues267s2712011enginfo:doi/10.11395/jjsem.11.s267著作権は日本実験力学会にある。利用は著作権の範囲内に限られる。publisher
