Abstract

The hypothesis that a thin nanometer-scale multilayered surface film could delay crack initiation and extend fatigue lives was evaluated by electrodepositing a Cu-Ni multilayer on Cu fatigue samples. A significant improvement in fatigue lives resulted and this improvement is attributed to properties of the multilayer coating.
