An investigation into frictional surface interactions and their effect on brake judder.
… chemical nature of the Transfer Film (T.F.) or Third-Body Layer (T.B.L.) formed at the friction interface of an automotive friction brake during off-brake motoring has been studied using Energy Dispersive X-ray (E.D.X.) analysis and Scanning Electron Microscopy (S.E.M.). Although these …

The Application of Laser Technology for Railroad Top of Rail (TOR) Friction Modifier Detection and Measurements
… optical sensors as they relate to detecting thin layers is presented, as well as a literature review of the significant aspect of surface roughness on optical signature. Both commercially available optical sensors and optical devices, such as independent lasers and detectors, are examined in a …

Analytical investigation of fretting wear with special emphasis on stress based models
… due to the shape, size and properties of the third body layer. A finite element model is created to study the changes in fundamental contact parameters in presence of third body particles and effects of number of third bodies and their properties on fretting contact is investigated. In …

Accurate Wheel-rail Dynamic Measurement using a Scaled Roller Rig
… at determining the effect of naturally generated third-body layer deposits (because of the wear of the wheel and/or roller) on creep or traction forces. The wheel-rail contact forces, also referred to as traction forces, are critical for all aspects of rail dynamics. These forces are quite complex …

Experimental Evaluation of Wheel-Rail Interaction
… at the surface—hence, referred to as "natural third-body layer"—is estimated to be a ferrous oxide. It has an opposite effect from the Top of Rail (ToR) friction modifiers that are deposited onto the rail surface to reduce friction in a controlled manner. Additionally, the results of the study …
