Structural metallic nanolaminates (coatings consisting of alternating layers of different metals) are being explored for applications ranging from high strength foils to wear resistant coatings due to their relatively high hardness. This study seeks to explore how the nanolaminate structure evolves after deposition due to sliding contact. Using two-component Cu-Nb and Cu-Ag model systems (with 20 and 100 nm individual layers), the scratch and wear behavior was characterized using linear reciprocating deformation testing. It was shown that the damage due to sliding (depth of wear track) and coefficient of friction both increased with increasing layer thickness.
