Phosphorus-based lubricant additives on iron with Machine Learning Interatomic Potentials
Paolo Restuccia, Enrico Pedretti, Francesca Benini +2
Phosphorus-based lubricant additives are used for protecting metallic contacts under boundary lubrication by forming surface films that reduce wear and friction. Despite their impo…
Zinc dialkyldithiophosphates adsorption and dissociation on ferrous substrates: an ab initio study
Francesca Benini, Paolo Restuccia, Maria Clelia Righi
Zinc dialkyldithiophosphates (ZDDPs) have been commonly used as anti-wear additives in the automotive industry for the past 80 years. The morphology, composition and structure of t…
Solid-Lubrication Performance of Ti3C2Tx -- Effect of Tribo-Chemistry and Exfoliation
Andreas Rosenkranz, Bo Wang, Dario Zambrano +7
Multi-layer Ti3C2Tx coatings have demonstrated an outstanding wear performance with excellent durability due to beneficial tribo-layers formed. However, the involved formation proc…
Xsorb: a software for identifying the most stable adsorption configuration and energy of a molecule on a crystal surface
Enrico Pedretti, Paolo Restuccia, M. Clelia Righi
Molecular adsorption is the first important step of many surface-mediated chemical processes, from catalysis to tribology. This phenomenon is controlled by physical/chemical intera…
A transferable prediction model of molecular adsorption on metals based on adsorbate and substrate properties
Paolo Restuccia, Ehsan A. Ahmad, Nicholas M. Harrison
Surface adsorption is one of the fundamental processes in numerous fields, including catalysis, environment, energy and medicine. The development of an adsorption model which provi…
Surface passivation by graphene in the lubrication of iron: A comparison with bronze
Diego Marchetto, Paolo Restuccia, Antonio Ballestrazzi +3
It has been recently reported that graphene is able to significantly reduce the friction coefficient of steel-on-steel sliding contacts. The microscopic origin of this behavior has…
Interfacial charge density and its connection to adhesion and frictional forces
M. Wolloch, G. Levita, P. Restuccia +1
We derive a connection between the intrinsic tribological properties and the electronic properties of a solid interface. In particular, we show that the adhesion and frictional for…
Size-dependent commensurability and its possible role in determining the frictional behavior of adsorbed systems
Paolo Restuccia, Mauro Ferrario, Pier Luigi Sivestrelli +2
Recent nanofriction experiments of xenon on graphene revealed that the slip onset can be induced by increasing the adsorbate coverage above a critical value, which depends on tempe…
Graphene and MoS2 interacting with water: a comparison by ab initio calculations
Giacomo Levita, Paolo Restuccia, M. C. Righi
Although very similar in many technological applications, graphene and MoS2 bear significant differences if exposed to humid environments. As an example, lubrication properties of…
Tribochemistry of graphene on iron and its possible role in lubrication of steel
Paolo Restuccia, M. C. Righi
Recent tribological experiments revealed that graphene is able to lubricate macroscale steel-on-steel sliding contacts very effectively both in dry and humid conditions. This effec…
