Due to the trend of down-sizing, machine elements are forced to operate under increasingly severe conditions. For lubricated systems this means that the lubricating films reduce to a level such that asperity interaction starts to play a role. For this reason, the full film lubrication of concentrated contacts on asperity level gained more attention. This field of research is generally denoted as micro-EHL. Compared to boundary lubricated micro contacts, fully lubricated asperity contacts result into a reduced coefficient of friction and a reduction of the corrosive and adhesive wear. This will have a positive effect on the life of the contacting surfaces. The purpose of this thesis is to determine the mechanisms involved in micro-EHL and in which way the parameters affect the film formation and friction.
