A micro-pitting model for spur gear contacts

International Journal of Fatigue, 2014
This paper proposes a physics-based model to predict the micro-pitting behavior on contact surfaces of spur gears operating under the mixed lubrication condition. The transient mixed elastohydrodynamic lubrication model of Li and Kahraman [1] developed for spur gears is employed to predict surface normal and tangential tractions, capturing the ...

Fabrication of micro pits based on megasonic assisted through-mask electrochemical micromachining

Ultrasonics, 2020
Through-mask electrochemical micromachining (TMEMM) is the primary method to fabricate micro pits with controlled size, location, and density. In order to improve the machining localization and deep etching capability in TMEMM process, a novel method which combined megasonic vibration to TMEMM process is presented in this paper.

Synergistic Boiling Enhancement on Hierarchical Micro-Pit/Carbon Nanotube Surfaces

ACS Applied Materials & Interfaces
Pool boiling offers exceptional heat transfer performance, making it crucial for advanced thermal management. However, simultaneously optimizing both critical heat flux (CHF) and heat transfer coefficient (HTC) is challenging due to the inherent trade-off between promoting bubble nucleation and mitigating detrimental bubble coalescence.
