The effect of third bodies on wear and friction at the wheel-rail interface
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2021The friction forces between the wheel and rail depend on a number of variables including the third body layer at the wheel–rail interface, the wheel and rail profiles, and the train dynamics. The third body layer significantly influences the damage mechanisms at the wheel-rail interface, especially wear, rolling contact fatigue (RCF), corrugations and ...

Third Body Effects in the Wear of Polyamide Materials
World Tribology Congress III, Volume 1, 2005This study deals with the micro-wear mechanisms of polyamide materials under reciprocating sliding conditions. Using the resources of in situ contact visualisation through transparent sapphire counterfaces, third body formation and flow processes have been monitored as a function of the sliding amplitude.

Role of third bodies in friction and wear of protective coatings
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2003The literature on protective tribological coatings often focuses on correlations with measurable coating properties (composition, structure, and mechanical) but ignores the mechanisms of friction and wear. In fact, long-lived coatings often survive because of third bodies that form inside the moving contact.

Third bodies in electrical contacts — Wear and electrical performance
2017 IEEE Holm Conference on Electrical Contacts, 2017Silver is a widely used protective coating material in electrical connectors, since it has good resistance to oxidation and thus is not affected by corrosion and fretting corrosion. The dominating mechanism for failure in silver coated electrical contacts is fretting wear.

Third-Body-Wear as a Risk Factor in Joint Endoprosthetics
Key Engineering Materials, 2005It is well known, that wear of the articulation partners of hip joint prostheses affect the long-term durability of the implants in vivo. The wear is dramatically increased if particles in the artificial joint gap act as third body. Those particles can also occur after a fracture of a ceramic component.

The third-body approach: A mechanical view of wear
Wear, 1984Abstract The third-body approach highlights the many features which are common to different types of materials in different types of rubbing contacts. It suggests that a picture which is globally coherent from a mechanical point of view, in that it obeys as a first step the laws of equilibrium and continuity, can be presented.

The Effect of the Third Body on the Fretting Wear Behavior of Coatings
Journal of Materials Engineering and Performance, 2002The formation, oxidation, and agglomeration of wear debris of coatings were investigated in this study. The rheology of the third body and its influence on the fretting wear behavior were studied in depth and systemically. The results showed that the shape and nature of the debris were the essential factors determining the mobility of the third body ...

Third body effects in the wear of polyamide: Micro-mechanisms and wear particles analysis
Wear, 2009Abstract The wear micro-mechanisms at a frictional interface between a polyamide 4,6 (PA 46) substrate and a spherical sapphire counterface have been investigated using in situ contact observation. Experiments were carried out under reciprocating sliding conditions with varying values of the overlap ratio, Δ , defined as the ratio of the ...

On the origins of third-body particle formation during adhesive wear
Wear, 2019Abstract The process of material removal during adhesive sliding contact (i.e. adhesive wear) remains one of the least understood areas in the field of tribology. The main reason for this limited understanding is that, direct observation and modeling of third body formation during adhesive contact present notorious challenges [1] .

Wear, 2003
Abstract Wear can be considered as a third body flow that is definitely ejected from the contact. This implies a source flow (particle detachment from first bodies) and an internal flow (displacement of these particles in the contact surface). The formation and fragmentation involved in surface tribological transformation (STT) is the main origin of ...
