ResumoAbstract Analytical tribology involves the recording of chemical, electronic and strctural information from wear debris and surfaces. Ultimately, the analysis can be performed in situ from the working interface, considerably increasing the level of interpretation of mechanisms. Three analytical techniques have been developed, namely, surface analysis (AES/XPS), Raman and absorption spectroscopies (XAS). Each approach is dedicated to specific studies in the field of dry friction, thin layer lubrication and boundary lubrication, respectively. The example of XAS is highlighted, to show how valuable information on friction-induced tribochemistry in the presence of anti-wear additives can be obtained. In this latter case, the approach has allowed some basic aspects of the anti-wear mechanisms of zinc dithiophosphate to be elucidated.
