Stress-augmented thermal activation: Tribology feels the force
Friction, 2018 In stress-augmented thermal activation, the activation energy barrier that controls the rate of atomic and molecular processes is reduced by the application of stress, with the result that the rate of these processes increases exponentially with applied ...

On the Commonality Between Theoretical Models for Fluid and Solid Friction, Wear and Tribochemistry [PDF]
, 2015 Tribology is concerned with the influence of mechanically applied forces on interfacial phenomena that accompany and control sliding. A wide range of models has been developed to describe these phenomena, which include frictional dissipation, wear and ...

Modelling interfacial tribochemistry in the mixed lubrication regime [PDF]
, 2018 The need to reduce the cost of components is driving more and more machine elements to operate under mixed lubrication conditions. With higher operating pressures, the lubricant film is becoming thinner and eventually reaches nanometre scales ...

An investigation of abrasive wear and corrosion behavior of surface repair of gray cast iron by SMAW
Journal of Materials Research and Technology, 2017 In this work, improving the abrasion–corrosion behavior of gray cast iron used in centrifugal pumps was studied. These pumps are usually made of gray cast iron (BS:1452Gr220) and are repaired by Shielded Metal Arc Welding (SMAW).

In-situ interfacial tribochemistry toward eliminating red-scale of silicon steel in friction process
, 2020 Irregularly striped red-scale defects are often formed on hot rolled silicon steel strips, and some still remain on the surface even after pickling. In this study, an in-situ interfacial tribochemistry concept was proposed to eliminate red-scale silicon ...
