Third Body Wear of UHMWPE-on-PEEK-OPTIMA™. [PDF]

Materials (Basel), 2020
PEEK-OPTIMA™ is being considered as an alternative to cobalt chrome (CoCr) in the femoral component of total knee replacements. To date, investigations of ultra-high molecular weight polyethylene (UHMWPE)-on-PEEK have shown an equivalent wear rate to conventional implant materials under standard conditions.

Roughness Evolution Induced by Third-Body Wear. [PDF]

Tribol Lett
AbstractSurface roughness is a key factor when it comes to friction and wear, as well as to other physical properties. These phenomena are controlled by mechanisms acting at small scales, in which the topography of apparently flat surfaces is revealed.

PMMA third-body wear after unicondylar knee arthroplasty decuples the UHMWPE wear particle generation in vitro. [PDF]

Biomed Res Int, 2015
Introduction. Overlooked polymethylmethacrylate after unicondylar knee arthroplasty can be a potential problem, since this might influence the generated wear particle size and morphology. The aim of this study was the analysis of polyethylene wear in a knee wear simulator for changes in size, morphology, and particle number after the addition of third ...

The Running-in of Lubricated Metal-Metal Contacts—A Review on Ultra-Low Wear Systems

Lubricants, 2018
The running-in of lubricated metal–metal contacts leading to ultra-low wear is inseparably connected with the formation of the third body and vice versa. Adequate tribological stressing provides the system with a power density that leads to complex

Tribofilms Forming in Oil-Lubricated Contacts

Lubricants, 2016
The subject of the present paper is the characterization of third bodies of run-in systems. By means of continuous friction and wear measurement, lubricated steel-steel and steel-aluminum contacts were evaluated.

A Simple Technique to Remove an Incarcerated Ceramic Liner in Revision Hip Arthroplasty

Arthroplasty Today, 2023
Extraction of a well-fixed ceramic liner during revision total hip arthroplasty can be technically challenging, particularly when acetabular fixation screws prevent en bloc removal of the shell and insert without causing collateral damage to the adjacent

Unusual cause of third-body wear in total hip arthroplasty

The Journal of Arthroplasty, 1997
A case of severe osteolysis caused by third-body wear using a Harris-Galante II cup (Zimmer, Warsaw, IN) is reported. The prosthesis was inserted in a 23-year-old man 4.5 years ago. At revision, 3 triangular tynes of the acetabular shell rim were found embedded in the polyethylene liner.

Characterization of third-body media particles and their effect on in vitro composite wear [PDF]

Dental Materials, 2012
The purpose of this study was to compare four medium particles currently used for in vitro composite wear testing (glass and PMMA beads and millet and poppy seeds).Particles were prepared as described in previous wear studies. Hardness of medium particles was measured with a nano-indentor, particle size was measured with a particle size analyzer, and ...

Temperature Effects on the Friction and Wear Behaviors of SiCp/A356 Composite against Semimetallic Materials

Advances in Materials Science and Engineering, 2017
Due to the low density and high temperature resistance, the SiCp/A356 composites have great potential for weight reduction and braking performance using the brake disc used in trains and automobiles.

Influence of Different Surface Texture Parameters on the Contact Performance of Piston Ring-Sleeve Friction Pair of Hydraulic Cylinders

Advances in Materials Science and Engineering, 2021
The surface texture, a major way to decrease friction and wear of the cylinder-piston ring friction pair, was conducted on cylinder-piston ring friction pair specimen using the orthogonal experimental design method to investigate the effect of different ...
