Exploring the fundamental mechanisms of hydrogen generation from a lubricated rubbing contact is critical step to mitigate premature failure mechanical elements. This work employs an in-situ uptake technique and molecular dynamics simulations study thermo-mechanical effects on in contacts. The measured AISI 52100 bearing steel at temperature 27 ◦C 85 under applied pressure 140 kPa 350 kPa. Expe...

This article describes fretting behavior of zirconia and silicon nitride balls on an electro-deposited coating. Fretting tests are performed using a ball-on-flat configuration. The evolution of the kinetic friction coefficient is determined, along with slip ratio. Experimental results show that the steady-state friction coefficient between ceramic balls (Si₃N₄ and ZrO₂) and an electro-deposited...
