Abstract
In this study, a duplex nano-corrugated and nanostructured surface was produced using an ultrasonic nanocrystalline surface modification (UNSM) technique. The objective of this study is to demonstrate the ability of UNSM technique to produce a desired nano-corrugated and nanostructured surface in order to improve the frictional behavior of Cu alloy. The experimental friction test results showed that the UNSM-treated specimen led to a lower friction coefficient compared to the untreated specimen, which may be attributed to the effects of UNSM technique.
