Which Design and Biomaterial Factors Affect Clinical Wear Performance of Total Disc Replacements? A Systematic Review [PDF]

, 2014
Background Total disc replacement was clinically introduced to reduce pain and preserve segmental motion of the lumbar and cervical spine. Previous case studies have reported on the wear and adverse local tissue reactions around artificial prostheses ...

Effect of work-rate on synergy of corrosion and wear of nickel-based 690 alloys under fretting conditions

Results in Engineering
The heat exchange tubes in the secondary steam generator of pressurized water reactor vibrate due to the impact of fluid, which results in collision leading to fretting wear. The work-rate can characterize random vibrations over time.

Contact Properties and Wear Behaviour of Nickel Based Superalloy René 80

Metals, 2016
A superalloy traditionally offers excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion or oxidation. However, a superalloy often also needs performance in terms of fretting resistance.

Fretting of CoCrMo and Ti6Al4V Alloys in Modular Prostheses [PDF]

, 2015
Implantation of a total hip replacements (THR) is an effective intervention in the management of arthritis. Modularity at the taper junction of THR was introduced in order to improve the ease with which the surgeon could modify the length of the taper ...

Design of a fretting fatigue test rig with compliant springs [PDF]

, 2013
Fretting is a small amplitude oscillatory movement which occurs between contacting bodies who are subjected to cyclic loading or vibrations. In the contact area arise stresses -normal and tangential- causing stress concentrations and surface degradation.
