Self-lubricating polytetrafluoroethylene-containing PEO (PEO-PTFE) composite coatings were prepared by vacuum impregnation on plasma electrolytic oxidized aluminum alloy with different cathodic voltages. The topography, microstructure and composition of the composite coatings were investigated by FE...
