Fretting–corrosion at the modular tapers interface: Inspection of standard ASTM F1875-98 [PDF]

, 2018
Interest in the degradation mechanisms at the modular tapers interfaces has been renewed due to increased reported cases of adverse reactions to metal debris and the appearance of wear and corrosion at the modular tapers interfaces at revision.

Effect of dynamic loading versus static loading on the frictional behavior of a UHMWPE pin in artificial biolubricants

Biosurface and Biotribology, 2017
To obtain reliable results from in vitro measurements on the tribological behavior of joint implant materials, the parameters of the measurements must simulate in vivo conditions.

Slipping friction of an optically and magnetically manipulated microsphere rolling at a glass-water interface

, 2008
The motion of submerged magnetic microspheres rolling at a glass-water interface has been studied using magnetic rotation and optical tweezers combined with bright-field microscopy particle tracking techniques.

Surface and subsurface changes as a result of tribocorrosion at the stem-neck interface of bi-modular prosthesis [PDF]

, 2017
This study presents a detailed multi-scale analysis of the degradation processes occurring on both the CoCrMo and TMZF alloy surfaces at different regions across the taper interface.

Methods for Evaluating Friction between Intravascular Device and Vascular Biomodel

Tribology Online
In recent years, endovascular treatments, in which a treatment device such as a catheter is inserted into a blood vessel to directly approach a lesion, have become increasingly popular worldwide.

The influence of textured surfaces on the tribological behaviour of hip replacements employing a mass conserving complementarity algorithm [PDF]

, 2015
The tribological behaviour of Metal-on-Metal (MoM) hip prostheses is a key factor for their success. In particular, wear is recognized to have a crucial role in the failure of a prosthesis and can have severe consequences on the patient’s health, e.g ...

Biotribological Wear Prediction of Alumina–Polymer Hip Prostheses Using Finite Element Analysis

Applied Mechanics
This study investigates the biotribological performance of alumina–UHMWPE and alumina–PEEK hip implant couples through finite element simulation (ANSYS v24) and statistical inference (STATA v17).
