Nanoscale friction and wear maps.
Friction and wear are part and parcel of all walks of life, and for interfaces that are in close or near contact, tribology and mechanics are supremely important. They can critically influence the efficient functioning of devices and components. Nanoscale friction force follows a complex nonlinear dependence on multiple, often interdependent, interfacial and material properties. Various studies...
متن کاملModelling Friction and Abrasive Wear of Elastomers
In order to properly model the friction and wear of elastomer materials, it is essential to understand some specific mechanical and tribological features. Mechanical characteristics of elastomer materials are different from those of metals and other relatively hard materials. Elastomers can bear large deformations, the stress-strain curves are non-linear, time and temperature dependent. When th...
متن کاملFriction and wear of restorative dental materials.
Many different instruments have been developed for the measurement of friction and wear.1-5 Often the instrument was designed to accommodate some particular type of material, environment, or test condition. Studies reported in the dental literature have been limited to wear measurements with simulated toothbrushing methods,6-9 or on prosthetic teeth mounted on an articulator.10 This study will ...
متن کاملFriction measurement in a hip wear simulator.
A torque measurement system was added to a widely used hip wear simulator, the biaxial rocking motion device. With the rotary transducer, the frictional torque about the drive axis of the biaxial rocking motion mechanism was measured. The principle of measuring the torque about the vertical axis above the prosthetic joint, used earlier in commercial biaxial rocking motion simulators, was shown ...
متن کاملFriction and wear of PTFE - a review
Polytetrafluoroethylene (PTFE) is an important engineering material. When rubbed or slid against a hard surface, PTFE exhibits a low coefficient of friction but a high rate of wear. These unique properties of the polymer have encouraged many mechanistic and physical examinations of the processes involved in the friction and wear of this polymer. A section of such work carried out over the past ...
