Abstract The addition of various extreme pressure and anti‐wear additives to lubricating oil is an important and effective way of reducing friction and wear. The application of chemico‐thermal treatments to material surfaces is another way to improve the tribological behaviour of rubbing pairs. The synergistic effects on the tribological behaviour of a tricresyl phosphate oil additive together with sulphurised, nitrided and oxy‐nitrided surfaces of 1045 steel were systematically studied on a ball‐on‐disc test machine. Good load bearing capacity and reduced friction and wear was obtained as a result. As well as presenting the promising results of this work here, the mechanism of this synergistic effect is discussed, based on micro‐analysis of the surface films by AES and XPS.
