In experimental work, it also enables repeated experiments to be carried out with the same topography and rather larger roughness features to be studied than would normally be present on real rough surfaces. Early film thickness measurements of rough surface features were made by Jackson and Cameron 1...

... in the contact was observed and some degree of separation between the two surfaces at the ridge tip was always detected. The film thicknesses measured by Kaneta for both bumps and ridges were in the 50 to 500 nm range so it was not possible to examine in any detail the thin film region. The authors...

... with a numerical pressure solver taking the initial film thickness measurement as input. The film thickness determination scheme is applied to an interesting phenomenon that can be observed at sliding conditions when the discrepancy occurred in the form of a deep and large dimple in the conjunction. Such a dimple...
