On page 4877, F. U. Renner, A. Bashir, M. Valtiner, and co-workers describe a star-like dealloying corrosion morphology that appears during the localized attack of smooth well-prepared Cu-Au surfaces. The surfaces are initially protected by thiol or selenol inhibitior films. Localized dealloying of Cu-Au produces nanoporous gold under stress and crystallographic cracks - thereby opening a new approach combining surface science with nanoscale mechanical testing.
第 4877 页,F. U. Renner、A. Bashir、M. Valtiner 及同事描述了一种在光滑预处理的 Cu-Au 表面局部腐蚀时出现的类星状脱合金腐蚀形态。这些表面最初由硫醇或硒醇抑制剂薄膜保护。Cu-Au 的局部脱合金在应力下产生纳米多孔金和结晶裂纹-从而开辟了将表面科学与纳米力学测试相结合的新途径。
