Two novel ashless and non‐phosphorus triazine derivatives, 2,4,6‐tri‐[N‐hydroxyethyl‐amino‐methylenesulfanyl]‐s‐triazine and 2,4,6‐tri‐[N,N‐bishydroxyethyl‐amino‐methylenesulfanyl]‐s‐triazine, were synthesised and their structures were analysed through elemental analysis. Their tribological behaviours in water were evaluated with a four‐ball machine, and the results indicate that their wear resistance and load‐carrying properties were excellent. The chemical features of the worn steel surface were observed and examined by means of inverted metallurgical microscopy and energy dispersive X‐ray spectroscopy. The analytical results of typical elements on the worn steel surface demonstrated, during the lubricating process, that the additives reacted with counter‐face metal and generated a boundary lubricating and protecting film containing elements of S, N and others, which contributes to improve the tribological properties of the test fluid.
