AB - The anti-wear performance and action mecha-nisms of zinc dithiophosphate (ZDDP) have been investi-gated under various test conditions. The Mini TractionMachine–Space Layer Imaging (MTM–SLIM) is a widelyused and useful method for monitoring tribofilm formationby ZDDPs. However, tests are generally carried out inmixed sliding–rolling conditions, typically between 50 %SRR (slide–roll ratio) and 100 % SRR. In this paper, theauthors describe an investigation of ZDDP film formationat SRRs much higher than 100 % SRR, including puresliding conditions using a novel MTM–SLIM technique. Athigh SRRs, ZDDP tribofilms form without damaging theball surfaces so long as both surfaces move above athreshold speed with respect to the contact, regardless ofwhether the two surfaces move in the same or opposingdirections. In pure sliding conditions, although the wornarea expands with time under pure sliding conditionsshowing that wear takes place, tribofilms are still built upthroughout a test and the ZDDP has a beneficial effect onwear rate. The very early stages of film formation arestudied to show that a tribofilm with a high concentrationof S is formed initially and then replaced with a film havinga high concentration of Zn and P.
