Friction and wear behaviour of polymer coatings in contact with rough surfaces under starved lubrication in CO_2 atmosphere

摘要

Various polymer coatings were investigated under sliding conditions in contact with rough grey cast iron surfaces under starved lubrication in CO_2 atmosphere. Contrary to previous studies focused on polymer coatings in contact with smooth surfaces which showed that PAI-based polymer coatings typically yielded the best wear and friction properties, in the present study where more abrasive conditions are present, PAEK-based polymer coatings provided the best performance.
