Original Abstract
Thin film colorimetric interferometry in the combination with phase shifting interferometry has been used for the detail experimental investigation of changes in real surface micro-geometry within EHD conjunction formed between a real, random, rough surface, steel ball and smooth glass disc. Three real roughness features were studied in detail – transverse ridge and 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.
Key words in English
