Originální abstrakt
Thin film colorimetric interferometry was used in combination with phase shifting interferometry for the detailed experimental investigation of changes in real surface microgeometry within the elastohydrodynamic conjunction formed between a real, random, rough surface, a steel ball and a smooth glass disc. Three real roughness features were studied in detail – the transverse ridge, transverse groove and longitudinal groove. The ridge was found to be heavily deformed within lubricated contact and its height increased with increasing rolling speed. For the transverse groove, a local reduction in film thickness at the leading edge was observed, while the longitudinal groove maintained its undeformed shape.

Kolorimetrická interferometrie a interferometrie s řízenou změnou fáze byly použity ke studiu chování povrchových nerovností v mazaném kontaktu. To umožnilo podrobně mapovat lokální změny v tloušťce mazacího filmu způsobené těmito nerovnostmi.
