N2 - This work aims to study the influence of porosity on local lubrication and friction characteristics of wet clutch. A thermal mixed lubrication model in plane contacts was developed and pin-on-disc tests were conducted on Universal Material Tester. Local pressure distribution, load sharing ratio, contact area ratio, local temperature rise and friction coefficient were analyzed. The results show that, in mixed lubrication, as the porosity increased, the pressure of hydrodynamic film reduced, while the pressure of asperity contacts increased. The normal load supported by asperity contacts increased and real contact area increased, and hence the friction coefficient increased.
