Problematic sites of third body embedment in polyethylene for total hip wear acceleration
Journal of Biomechanics, 2006A computational model was developed to identify the sites of third body particle embedment in a total hip acetabular component surface that are most problematic in terms of roughening the overpassing regions of the femoral head counterface, leading in turn to most severely accelerated polyethylene wear.

Third Body Formation and the Wear of PTFE Fibre-Based Dry Bearings
Journal of Lubrication Technology, 1980Dry bearing tests have been made with a PTFE fibre/glass fibre/phenolic resin composite against stainless steel to examine the influence of time of sliding, counterface roughness and load. The worn surfaces were examined by optical and scanning electron microscopy, energy dispersive analysis of X-rays (EDAX) and X-ray photoelectron spectroscopy (ESCA).

Electrochemical control of wear: a third body approach
2003A phenomenological description for tribocorrosion is developed by including electrochemical corrosion aspects into a third body approach. The developed third body approach stresses the relevance of electrochemical phenomena such as dissolution or formation of stable oxides for the overall wear process.

Development of a Model for Testing Third Body Wear of UHMWPE Acetabular Components
Journal of ASTM International, 2004Abstract The purpose of this paper is to describe the development of a new wear test protocol utilizing third body particulate debris in order to assess conventional and highly cross-linked polyethylene components. A series of tests were performed using the Boston Hip Simulator to evaluate different types of particles for possible use ...

A model of third body abrasive friction and wear in hot metal forming
Wear, 1999A model of friction accounting for third body particles at the contact interface is derived from a simple micro-mechanical model of a particle interacting with a hard tool surface and a soft workpiece surface. Also a wear law coupled with this friction model is proposed.

Paper IV (i) Third Bodies in Wear Models
1992Third bodies are present between virtually all practical sliding systems. Third body substances therefore control the sliding resistance and the stresses imposed on surfaces. Their properties should thus be the basis for the formulation of predictive equations for friction and wear.

Third body effects on friction and wear during fretting of steel contacts
Tribology International, 2011Abstract Fretting wear proceeds through particle detachment from the contacting surfaces which, while trapped in the contact zone, can affect the frictional and wear response. Ball-on-flat fretting experiments were carried out between steel specimens under gross slip regime. A transition in the coefficient of friction was linked to a critical contact

Effect of Microseparation and Third-Body Particles on Dual-Mobility Crosslinked Hip Liner Wear
The Journal of Arthroplasty, 2014Large heads have been recommended to reduce the risk of dislocation after total hip arthroplasty. One of the issues with larger heads is the risk of increased wear and damage in thin polyethylene liners. Dual-mobility liners have been proposed as an alternative to large heads.
