..., with an appropriate choice of metals, it has the potential to achieve low adhesion, low contact resistance, and high durability. The effect of the layer thickness on the adhesive contact was investigated. In particular the influences of layer thickness on the pull-off force, maximum contact radius, and contact...

.... An electric field was imposed between the ball and disk to monitor the tribochemical reaction by means of “contact resistance.” These ionic liquids substituted cyclophosphazene derivatives present lower friction coefficient and wear volume loss than tetrakis-(3-trifluoromethylphenoxy)-bis(4-fluorophenoxy...

... aluminum alloy; the contact resistance is considered mainly due to the surface oxide film. The simulation results indicate that the transient contact model is able to capture the history of plastic deformation accumulation and the material melting inception. Conceptual figure of the sliding electrical...

.... A simple electrical contact resistance (ECR) circuit, designed to detect in situ the formation of insulating tribofilms 5 6 11 , was used to track the evolution of tribofilm formation. The duration of each test was approximately 13 min. Flat circular disk and ball bearing specimens...

... observed through the reversible and irreversible decreases, respectively, of the contact resistance upon loading. Elastic deformation was dominant at the maximum stress. Plastic deformation progressed and then saturated upon stress cycling. Contributed by the Tribology Division for publication...
