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.

Third body damage and wear in arthroplasty bearing materials: A review of laboratory methods [PDF]
Biomaterials and Biosystems, 2021 Third body wear of arthroplasty bearing materials can occur when hard particles such as bone, bone cement or metal particles become trapped between the articulating surfaces. This can accelerate overall implant wear, potentially leading to early failure.

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

Third Body Wear of an All-Polymer, PEEK-OPTIMA™ on Ultra-High-Molecular-Weight Polyethylene Total Knee Replacement [PDF]
BioengineeringExperimental wear simulation of a PEEK-OPTIMA™ polymer-on-UHMWPE total knee replacement has shown equivalent UHMWPE wear to conventional knee replacement materials (cobalt chrome-on-UHMWPE) when tested in a clean environment. The aim of this study was to

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 ...

Assessing the relationship between incisor wear, age, and body condition in Dohne Merino ewes (Ovis aries) [PDF]
Animal WelfareSheep (Ovis aries) are stoic, prey animals that have evolved to mask signs of pain and vulnerability, making behavioural indicators of poor welfare difficult to detect.

Detecting vorticity in cohesive deformable granular material [PDF]
EPJ Web of Conferences, 2021 Numerical models of granular materials are useful in tribology, and can be used to predict wear and friction in contacts. DEM-like simulations are used to model particles of third-body, which are partly wear debris from rubbing bodies.

Friction and Wear Properties of Wheat Straw Powder Third Body on Steel-Steel Friction Pair
Agriculture, 2022 Third body plant fibers have an important influence on the friction and wear properties of metal friction pairs. In this study, wheat straw powder with different particle sizes was prepared, and a pin-on-disk friction tester was employed to evaluate the ...
