Thermodynamic and kinetic analyses of probable chemical reactions in the tribocontact zone and the effect of heavy pressure on evolution of adsorption processes

A Semi-deterministic Wear Model Considering the Effect of Zinc Dialkyl Dithiophosphate Tribofilm

“…The formation of the tribofilm is assumed to be due to chemical reactions at the interface and follows the kinetics of tribochemical reactions, which are activated not only by temperature but also by mechanical rubbing [36][37][38]. Active collision theories used by Bulgarevich et al [36,37] to explain tribochemical reactions were adopted in the development of the tribofilm growth model used here.…”

Active collision theories used by Bulgarevich et al [36,37] to explain tribochemical reactions were adopted in the development of the tribofilm growth model used here. It has been suggested that tribofilm removal can be as important as tribofilm formation [40,41], so the tribofilm formation model is augmented with a phenomenological term to account for concurrent removal of the tribofilms.…”

A Deterministic Stress-Activated Model for Tribo-Film Growth and Wear Simulation

“…However, Bulgarevich et al [19] showed that this leads to very low (unrealistic) activation energies. In a different paper, Bulgarevich et al [20] introduced a stress dependence to the Arrhenius equation by means of a multiplication factor [20]. Very recently, Gosvami et al [5] employed an Arrhenius equation where the activation energy was made stress-dependent.…”

“…Andersson et al [23] only included the influence of temperature and employed Arrhenius' equation, following So et al [24]. Ghanbarzadeh et al [25] proposed a semi-deterministic model for tribo-film growth following Bulgarevich et al [20]. The influence of the stress was taken into through a correction factor.…”

Generation of wear particles in lubricated contcats during running-in

“…Ghanbarzadeh et al [108] proposed a semi-deterministic model for tribo-film growth, based on a modified Arrhenius equation, as proposed by Bulgarevich et al [109]. The influence of the stress was taken into account indirectly, through a prefactor.…”
