Roughness effects in concentrated contact from full to mixed lubrication

Popis výsledku v původním jazyce

Stirred up by a quest for higher energy efficiency, there is an evident trend of lubricant film thinning in recent decades. As a result, an impact of a surface roughness on the contact performance in machine components is increasing steadily. Surface roughness influences film thickness, pressure distribution and friction produced by an EHL contact. It is well known that simple approach how to deal with roughness is often not sufficient due to roughness deformation and roughness influence on film thickness. Therefore, it is important to get know more about effects connected with specific character of surface features inside the contact. This study presents an overview of recent film thickness experiments showing phenomena connected with several kinds of roughness features. Specific focus is given to its magnitude of deformation and affected film thickness to give a better image of real surfaces separation.
