- This paper reports detailed experimentation of rolling/sliding hardened and ground disk contacts simulating mixed lubrication in power transmission gears. New high-frequency contact resistance measurements show that rough surface interactions are repeatable and mechanistic, demonstrating asperity contact variation. This reinforces numerical model results which show asperity interaction is highly transient (10.1177/0954406215606934). Asperity contact and measured friction levels are shown to be clearly related to specific film thickness, an important step in understanding friction in these conditions. New investigations into thermal effects highlight the importance of contact temperature changes in otherwise steady-state conditions. The paper led to an invited IoP presentation (www.iop.org/physics-community/special-interest-groups/tribology-group#gref).
