The influence of tribosystem variables such as humidity, velocity and lifetime on frictional and electrical response were also compared with specific wear energy calculation method. The main findings of both tribological and electrical behaviors include the dissipated energy and the micro-slip dielectric failures that can be linked to the properties of self-lubricating layers, which depend also on the working media. In this framework, the electro-tribological evaluation provides an electrical monitoring tool for coating premature wear detection in real time.13259461enginfo:eu-repo/semantics/restrictedAccessjournal article10.1016/j.triboint.2019.106086Electro-tribologyElectrical contact resistanceDissipated energyWear sensingElectro-tribologyElectrical contact resistanceDissipated energyWear sensingMechanics of MaterialsMechanical EngineeringSurfaces and InterfacesSurfaces, Coatings and FilmsFunding InfoThis work was financially supported by the INCT-INES (CNPq) [grant number 554336/2014-0], CAPES, FAPESP [grant number 2019/00757- 0] and nG-17 and Frontiers (Elkartek funding from the Economic Development Department at the Basque Government) projects.
