Third‐Body Reality – Consequences and Use of the Third‐Body Concept to Solve Friction and Wear Problems

Dependence of tribofilm characteristics on the running-in behavior of aluminum–silicon alloys

“…The difference in the microstructural evolution for the two contact pressures may be explained by the differences in the flow of the tribological circuit [32,33] comprising the source flow (i.e., material transformation from the first body into the third body), the internal flow (i.e., material movement within the contact), the ejection flow (i.e., ejected material), recirculation flow (i.e., material reintroduced to the interface), and the wear flow (i.e., permanently removed material). Considering the flat-onflat sliding contact in our study, the higher contact pressure leads to a larger and more uniform contact area resulting initially in more contacting asperities.…”

“…A complete tribological investigation procedure has thus been developed and presented [30]. The 3rd body concept [74][75][76] was extended from solid flows to include gas flows inside the contact. The resulting global 3rd body concept was then used as a formalization tool to conserve the dynamics of the mechanic-physic-chemical mechanisms governing the tribological behavior.…”

“…The velocity accommodation is then linked to equilibrium between plastic deformations of the trapped 3rd body layer and interface sliding between the 3rd body layer and one or both the 1st bodies initially in contact [17]. The reader can also find detailed explanation and description of the 3rd body concept in [18][19][20].…”
