This study aims to determine how friction-induced transferred film affects the friction properties of nanostripe structures. In this report, two types of nanostripe structures were used. One was composed of Au and Cr and the other was Ag and Cr. First, each nanostripe substrate was rubbed using a ball-on-plate friction machine. The friction coefficient of Ag-3Cr was lower than that of Au-Cr when friction tests with Al2O3 ball took place in a vacuum environment. The friction coefficient of Au-Cr decreased at one time, but then increased and did not stabilize. In contrast, the friction coefficient of Ag-3Cr was stable at 0.2 from around 200 times. Then, the wear track on the nanostripe structure was measured using conductive atomic force microscopy(c-AFM). c-AFM results showed that the current flowable region was wider for Au-Cr than for Ag-3Cr. In the future, we will investigate the influence of the transfer film on friction reduction and the distribution of film thickness by measuring friction in the wear traces using AFM.
