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

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.

Mechanisms of oxide dependent tribological behavior in Ti / Steel sliding and influence of nanostructured surfaces [PDF]
MATEC Web of Conferences, 2020 The tribological behavior of pure titanium having coarse-grained or nanostructured surfaces has been investigated against a steel ball moved with an alternative motion.

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.
