Zinc dialkyldithiophosphate (ZDDP) is an anti-wear additive, commonly used in engine lubricants. Under severe conditions of friction, it forms a tribofilm on steel surfaces. ZDDP tribofilm is mainly composed of zinc polyphosphates and its structure varies gradually over the height of the film: short phosphate chains at the metal surface and longer phosphate chains at the top of the film. Several studies have been conducted to understand the mechanism by which the additive may lead to the formation of this gradient of the phosphate chain length. The influence of pressure, shear stress, nature surfaces and temperature on the structure of zinc orthophosphate and zinc metaphosphate were investigated, to improve the understanding of their action...
