“…Due to this the well-known potential approximations like the Morse and LJ ones remain popular, too [384,385]. Note: For complex materials we have calculated C 6 using average atomic concentrations.…”

“…Perhaps, more important MD results obtained to date are those concerning computer simulations of the adsorbate friction [314,381,384,385], realising the importance of an interplay between the commensurate and incommensurate structure transitions of the contacting surfaces. As it has been pointed out in several studies [141 to 144], the frictional force between the surfaces having incommensurate periods should be many orders of magnitude smaller than for commensurate ones.…”

“…Thus, Tamura et al [384] have studied the friction between talc(001) surfaces under realistic conditions: at a pressure of 1 atm and a temperature of 300 K. Their model consists of two talc(001) slabs arranged along the z axes. Each slab is built up from seven layers including one Mg layer between two Si layers.…”

A review is given of the present day problems related with experimental and theoretical studies in nanotribology, a new apatterning branch of physics, which pertains to investigations of the atomicscale friction, adhesion, wear and lubrication. When analysing the experimental results a major point of interest is related with ªdryº adhesion friction between the tip of an atomic force microscope and an atomically smooth surface. However, many other physical effects are considered, too, such as chemical ones, triboemission of particles, conduction in metallic nanocontacts, etc. For the first time, some new results in theoretical elaborations of adhesional (static) and dynamical (velocity-proportional) friction are discussed, as well as some results obtained using the computer simulations. A brief discussion of nanostructural friction measured with the quartz crystal microbalance technique and the surface-force apparatus is also given.

“…For MD simulations, the interaction potential depends on materials of two sliding components and interfacial conditions. There are studies [36][37][38][39][40][41][46][47][48][49] to investigate effects of various potential parameters used as an interaction potential on chip formation for atomicscale tribological conditions. Robbins et al [46][47] has studied the static and kinetic friction when an adsorbed surface layers existing between two sliding components, where the effects of potential parameters of the Lennard-Jones potential has been investigated.…”

Molecular dynamics studies of atomic-scale tribological characteristics for different sliding systems

A slider-slab sliding model for hard-to-soft and soft-to-soft sliding systems with abrasive and non-abrasive wear conditions is used to investigate atomic-scale friction. The molecular dynamics simulation uses the Morse potential to calculate interatomic forces between atoms. Separation distance between the slider and the slab is changed to simulate repulsive and attractive interactive force fields exerted on interface between two sliding components. Effects of the interaction potential parameters on the sliding friction are investigated. The relationship of frictional force, normal force and temperature rise of the slider and the slab during sliding are established. Comparison of the hard-to-soft and the soft-to-soft sliding system are carried out and shows different tribological phenomena.
