        Research Progress of Interface Conditions and Tribological Reactions: A Review

        Huajie Tang,Jianlin Sun,Jiaqi He,Ping Wu 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.94 No.-

        Tribology plays a crucial role in progress of industry and engineering. The dependence of interfaceconditions and interfacial reactions provides the strategies for friction reduction as well as anti-wear inindustrial processes. That is to modify the surface structure of materials or tune the properties oflubricants. This review provides an overview on the important interface conditions and surface-inducedtribological reactions with emphasis on the underlying of their formation and action mechanism. Thetribological features of asperity, debris and surface texture arefirstly dictated. Then the main surfaceinducedphysicochemical reactions including wetting/dewetting, deposition/adsorption are discussed. Inparticular, the thermal, mechanical and electrical effects that trigger tribochemical reactions are alsoaddressed. Finally, some deficiencies in related investigations are summarized, with perspectives for thedevelopment of tribology in both science research and industrial application.

        Advances of molecular dynamics simulation in tribochemistry and lubrication investigations: A review

        Jiaqi He,Huajie Tang,Chenglong Wang 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.126 No.-

        As a hot topic in recent years, molecular dynamics (MD) simulation has become an effective tool in tribochemistryand lubrication investigations, which provides unique insight on dealing with these issues fromatomic scale. This review paper presents an overview of recent MD simulation studies on revealing the frictionlaws, wear mechanism and lubrication performance of materials and lubricants, which aims to provideguidance and reference for future theoretical investigations on revealing the essence of friction, wear andlubrication. MD simulation researches upon the tribology, tribochemistry and lubrication are summarized,focusing on the field of friction and wear mechanism, nano-tribology, liquid lubricants, lubricant additives,superlubricity phenomenon, etc. Besides, the challenges and problems remain to be considered, as well asfuture development directions of MD simulation are briefly discussed.With the help of MD method, the obstacleto tribology research caused by insufficient experimental methods can be reduced in the future.
