Graphite-like carbon films are formed as tribofilms when polyphenylether lubricants are rubbed. To investigate the formation mechanism of graphite-like carbon films, tetraphenyl ether (5P4E) oil was irradiated with electron beams and the structural changes were analyzed by Raman spectroscopy. As a result, it was found that a component with a graphite structure was formed in the 5P4E oil. Finally, it was estimated that the triboelectrons generated by friction are captured by the polyphenyl ether molecules, resulting in the formation of graphite-like carbon as tribofilms.
