Puckering stick-slip friction induced by a sliding nanoscale contact.
An atomic force microscope reveals that the sliding of a nanotip on a graphite surface occurs through a nanoscale stick-slip mechanism. The angle between the sliding direction and a stiff crystallographic axis determines the periodicity of the slip events defining domains of various friction properties. The experimental data are interpreted using the reaction rate theory, with the energy barrie...
متن کاملSliding Friction Contact Stiffness Model of Involute Arc Cylindrical Gear Based on Fractal Theory
Gear’s normal contact stiffness played an important role in the mechanical equipment. In this paper, the M-B fractal model is modified and the contact surface coefficient is put forward to set up the fractal model, considering the influence of friction, which could be used to calculate accurately the involute arc cylindrical gears’ normal contact stiffness based on the fractal theory and Hertz ...
متن کاملA Triboscopic Investigation of the Wear and Friction of MoS2 in a Reciprocating Sliding Contact
Reciprocating sliding tests with ball-on-flat geometry were performed on a duplex coating at low speeds in moist air (RH=60%). The coating, 55 nm MoS2 on 35 nm of TiN, was deposited by ion-beam assisted deposition onto a steel substrate. Friction coefficient (μ) and electrical contact resistance (Rc) measurements were recorded at ~2μm intervals along the track; these spatially resolved measurem...
متن کاملEffects of mechanical properties and surface friction on elasto-plastic sliding contact
Indentation hardness has been used extensively for material characterization and many recent computational studies have established quantitative relationships between elasto-plastic mechanical properties and the response in instrumented indentation. In contrast, very few studies have systematically quantified the effect of the plastic deformation characteristics on the frictional sliding respon...
متن کاملEvaluation of sliding friction and contact mechanics of elastomers based on dynamic-mechanical analysis.
The paper presents a combined experimental and theoretical approach to the understanding of hysteresis and adhesion contributions to rubber friction on dry and lubricated rough surfaces. Based on a proper analysis of the temperature- and frequency-dependent behaviors of nonlinear viscoelastic materials such as filler reinforced elastomer materials, master curves for the viscoelastic moduli are ...
