For applications at low switching loads, contact layers with thicknesses in the range of just a few micrometers are widely used. For testing such thin layers, the actual coating properties must be distinguished from the functional properties. Coating properties include, besides others, porosity, hardness and ductility. Depending on the application, the most important function properties are for example frictional wear, contact resistance, material transfer or contact welding behavior. Besides these, other technological properties such...
