Sažetak

This paper reviews the advances in the study of mixed lubrication in recent years, both in theoretical modelling and in experiments, especially those marking substantial progress. The advances support the mode of mixed lubrication proposed by the author more than ten years ago which exhibited thinning, mixed and partial films and mixed contacts in modern mixed lubrication under severe operating conditions. The paper outlines recently achieved progress in the field, which revealed new phenomenon such as: the elastoplastic deformation of the surface asperities, the boundary film interfacial slippage, the boundary lubrication effect and the interfacial shear stress effect on the contact surface deformation. Also, the mixed lubrication with designed surface roughness and the load-carrying mechanism of mixed lubrication are reviewed.
