Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405565-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>On self‐assembled monolayer‐covered Cu–Au substrates, </bold> localized volume shrinkage at initial dealloying sites leads to cracks within the attacked regions. It is started from well‐controlled surface structures to gain fundamental insights in the driving mechanisms of localized corrosion and crack formation. Both the crack density and the crack morphology are critically dependent on surface orientation, crystallography, and inhibitor molecule species. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2h30rm4c" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
