Abstract
The purpose of the present study is to examine the antiwear properties of some cyclic phosphates and phosphites and to compare them with a noncyclic phosphite and a commonly used oil additive zinc O, O-diisooctylphosphorodithioate (ZnDTP). A number of cyclic phosphates and phosphites were tested on a four-ball machine using various temperatures, loads, speeds and base oils. It was observed that cyclic phosphites possess better antiwear properties than cyclic phosphates. Of the phosphites, the compound containing sulphur was more effective than the corresponding molecule with oxygen in place of sulphur and it gave better results. This superior performance was observed in base oils A, B and C. In comparison with ZnDTP, this compound possesses significantly superior antiwear properties at high temperatures and loads.
