The synthesis and antiwear action of tungsten dithiolate

Abstract

AbstractTungsten dithiolate was synthesised by the reaction of WO3 with toluene‐3,4‐dithiol (abbreviated to H2TDT), and its extreme‐pressure and antiwear properties were investigated on a four‐ball tester. The results showed that it possesses fairly good extreme‐pressure and antiwear abilities. Based on analytical results obtained by Scanning Auger Microprobe and Scanning Electron Microscopy, as well as Electron Ionisation Mass Spectra fragments, the antiwear mechanism of WTDT suggested that a permeating layer containing WC, WS2, and WO3 played an important role in the antiwear and friction‐reducing action.
