Abstract
To develop new solid lubricant films based on low friction multilayer model, nanoperiod Au and Ag multilayer films are deposited. The results of nanoindentation tests reveal that multilayer films exhibit a higher elastic modulus, a higher hardness and a lower modulus of dissipation energy than single layer films. From the ball on disc tribological test, the friction coefficient of multilayer film μ is as low as ∼0·05. The friction life cycle of the nanoperiod multilayer films is longer than those of single layer films. The electrical resistivity of nanoperiod multilayer films induced by sliding is a little higher, and the change in that is less than that of single layer films.
