Tribological Study of Xanthate-Containing Acetic Ester as Additives in Hydrogenated Oil

Abstract:

A novel ester derivative, dodecyl xanthate acetic dodecyl xanthate ester(DXAD) was synthesized and it’s tribological behaviors as additives in hydrogenated oil, were evaluated using a four-ball tester. Results show that the compound possesses good antiwear performance, extreme pressure capacity, and good friction-reducing property. The action mechanism was estimated through analysis of the worn surface with X-ray photoelectron spectroscopy (XPS) and Scanning Electron Microscope (SEM). The results of XPS and SEM analyses illustrate that the prepared compound as an additive in hydrogenated oil forms a protective film containing ferric sulfide and ferric sulfate compounds on the rubbed surface.
