Wear properties of PTFE polymer coated carbon steel using atmospheric and RF low pressure plasma

Summary form only given. Polytetrafluoroethylene (PTFE) polymer material was deposited onto surface of heat treated AISI 1050 carbon steel by atmospheric and vacumm plasma system with different plasma parametres (treatment time, gas type, frequency, power and pressure). Wear tests of coated surface were conducted by using a tribotester. After the deposition surface morphology of samples were analysed by energy-dispersive X-ray spectroscopy (EDS), Scanning Electron Microscope (SEM), Atomic Force Microscope (AFM) and Optical Microscope (OM), it was found that under atmospheric pressure plasma treatment conditions PTFE coated substrates had a friction coeifficent that was twice as much as that for the low pressure RF plasma treatment conditions.
