Chemical effects on the sliding friction of Ag and Au(111)
Friction, 2017 We have investigated the sliding friction behavior of metallic couples with different enthalpy of mixing or reaction by friction force microscopy. Comparing the friction behavior of miscible and immiscible couples we find that in the first case friction ...

Friction vs. Area Scaling of Superlubric NaCl-Particles on Graphite
Lubricants, 2019 Structural lubricity is an intriguing tribological concept, where extremely low friction is anticipated, if two surfaces in relative motion do not share the same lattice structure and consequently instabilities originating from interlocking surface ...

Importance of surface oxide for the tribology of a Zr-based metallic glass
Friction, 2017 Thermally grown surface oxide layers dominate the single-asperity tribological behavior of a Zr60Cu30Al10 glass. Increase in oxidation time leads to an increased contribution of shearing and a corresponding decreased contribution of ploughing to friction.

Velocity dependence of sliding friction on a crystalline surface
Beilstein Journal of Nanotechnology, 2017 We introduce and study a minimal 1D model for the simulation of dynamic friction and dissipation at the atomic scale. This model consists of a point mass (slider) that moves over and interacts weakly with a linear chain of particles interconnected by ...

Rigorous derivation of diffusion equation for submonolayer lubricant film
Nihon Kikai Gakkai ronbunshu, 2018 In magnetic hard disk drives, it is important to secure the stability and durability of head–disk interface in relation to a submonolayer lubricant film because the spacing between a head and lubricant surface has to be reduced to ~0.5 nm to achieve a ...
