Abstract

Correlations between deposition parameters of palladium films deposited from ionic liquids, microstructural properties, and the wear behavior are identified. The wear volume and calotte depths decrease, if tensile residual stresses are reduced. Cracks within the layer influence the wear resistance only marginally. Furthermore, results indicate that low pulse frequencies and long pulse lengths during deposition have positive effects on the wear results.
