    In recent years, DLC coatings are becoming extensively used in automotive applications for internal combustion engines, where ZDDP is the key additive. In spite of research work so far the mechanism ... of formation, and structure of the ZDDP derived tribofilm on DLC, the understanding is still very limited. Accordingly, in this work, the chemical structure of the ZDDP thermal film during static thermal tests at 150°, i.e. without any tribological action, on Si-DLC and H-DLC, as well as steel as reference, at different times and ZDDP concentrations have been investigated. The ATR-FTIR and XPS spectroscopies have been used for the chemical characterization of these thermal films. The results have indicated that the chemical structure of ZDDP thermal films on the steel surface is different form the DLCs, while different times and ZDDP concentrations do not affect the chemical structure of the ZDDP thermal film on each individual surface/substrate. In addition, the results have indicated that the thickness of the thermal film is greater on the steel than on the DLC and is linear with the concentration, which indicates the uniformity of the chemical structure of the films.
