An ad-hoc fretting wear tribotester design for thin steel wires

MATEC Web of Conferences, 2018
Steel wire ropes experience fretting wear damage when the rope runs over a sheave promoting an oscillatory motion between the wires. Consequently, wear scars appear between the contacting wires leading to an increase of the stress field and the following

Effect of torsional angle on the fretting wear behavior and fracture failure mechanism of steel wires with spiral contact structure

Journal of Materials Research and Technology
The fretting wear of steel wire will reduce the service life of wire rope and severely threaten the safety of mine hoisting. To investigate the influence of torsion on the fretting wear behavior of steel wire, the fretting wear tests of steel wires with ...

Review and classification of fretting fatigue test rigs [PDF]

, 2011
There is no standard or generally accepted test rig for fretting fatigue experiments. Therefore, researchers adopt an existing concept, or build a new test rig that meets their specific requirements.

Effect of laser remelting on microstructure and fretting wear properties of APS Al2O3/Y2O3 composite coatings on TC6 titanium alloy

Journal of Materials Research and Technology
To enhance the fretting wear resistance of TC6 titanium alloy, an Al2O3/Y2O3 (81.5 mol.%: 18.5 mol.%) composite coating was prepared on the TC6 substrate using the APS process, followed by laser remelting. The microstructure and fretting wear behavior of

The effect of different assembly loads on taper junction fretting wear in total hip replacements [PDF]

Variability in the magnitude of the impaction force applied by surgeons to assemble a hip prosthetic head to a femoral stem could be a cause of increased wear in taper junctions. This study investigates the effect of varying the magnitude of the assembly

A computational approach to fretting wear prediction at the head-stem taper junction of total hip replacements [PDF]

Wear is one of the main reasons for failure of modular total hip replacements. Recent evidence suggests that fretting wear occurs at the taper junction which provides fixation between the prosthesis femoral head and stem components.
