    "abstract": "Nanoindentation tests were performed at several temperatures (24 to 80degC)\non one antiwear zinc dialkyl-dithiophosphate (ZDTP) tribofilm using a\nNanoindenter XP (R) entirely set into a climatic chamber. Mechanical properties\nof the tribofilm were determined using a simple model. AFM observations were\nconducted to estimate the order of magnitude of the film\u0027s thickness. The\neffect of applied pressure on the elastic properties was demonstrated and taken\ninto account in the present analysis. The use of the F/S^2 parameter,\nindependent of contact geometry, revealed a hardness dependency upon\ntemperature. Furthermore, careful AFM observations of the residual pile-up\nproduced by plastic flow around the indents pointed out the evolution of the\nfilm deformation process with temperature.",
