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.

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 ...

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.

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 ...

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 ...

How Third-Body Processes Affect Friction and Wear
MRS Bulletin, 1998Materials designed for rolling or sliding contact, like corrosion-resistant materials, can provide great cost savings to industry. So why can't such “tribomaterials” be designed based on materials properties that control friction and wear? In recent years, it has become clear that the properties we need to understand are not only those of the starting ...

Al2O3–ZrO2 debris life cycle during wear: effects of the third body on wear and friction
Wear, 1997Abstract Wear debris of alumina–zirconia materials generated during wear by abrasion and chipping (ring on disk) were analyzed in order to study their life cycle and their effects on wear and friction. When generated in the contact, wear debris contributed to redistribute the applied load on more contact points and absorbed a part of the energy ...
