    Experimental Study of Real Asperities Behaviour within Lubricated Contacts

  • Original language description

    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 increasiing 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.

    Experimentální studium chování povrchových nerovností v mazaných kontaktech

  • Czech description

    Kolorimetrická interferometrie a interferometrie s řízenou změnou fáze byly použity pro podrobné studium změn topografie třecích povrchů v mazaných kontaktech. Tři povrchové nerovnosti byly studovány detailně - příčně a podélně orientovaná rýha a příčnýpráh. U příčného práhu byla pozorována významná elastická deformace v mazaném kontaktu, která se snižovala s rostoucí rychlostí třecích povrchů.
