...Jiaxin Zheng; Sen Jiang; Guangneng Dong Purpose Scuffing is a severe form of adhesive wear that can lead to catastrophic surface damage in tribological systems. This paper aims to investigate the failure mechanism of scuffing and to propose an effective surface engineering strategy to enhance...

... with the simulation prediction results. The results lay a foundation for the working life design of spiral bevel gear in helicopter transmission system under starved lubrication. Castro and Seabra (2018) developed a new scuffing parameter (mass temperature) for gears lubricated with mineral base oils...

...Bora Lee; Yonghun Yu; Yong-Joo Cho Purpose This paper aims to propose a new scuffing model caused by the depletion of additives in boundary lubrication condition. Design/methodology/approach The differential equation governing the distribution of additive content in the fluid film was used...

... especially pronounced during running-in. Design/methodology/approach Experiments at a twin-disk and gear test rig were combined with chemical, structural and mechanical tribofilm characterization by surface analysis. Pitting lifetime, scuffing load carrying capacity and friction of ground spur gears were...

... wear caused by misalignment. Scanning electron microscope (SEM) images examine chuck, spherical and flat platelet particles, and confirm the presence of fatigue (pitting) and adhesion (scuffing) wear mechanism. Energy-dispersive X-ray spectroscopy analysis of SEM particles traces carbon (C) and iron...

...Lukasz Wojciechowski; Radomir Majchrowski; Thomas G. Mathia Purpose Boundary lubrication cannot provide long-term protection against scuffing. Therefore, it is fundamental to recognise the breaking point of the boundary layer that activates scuffing. Based on this assumption, three-dimensional (3D...

...Remigiusz Michalczewski; Witold Piekoszewski; Waldemar Tuszynski; Marian Szczerek Purpose – The purpose of this paper was to explore the mechanisms of scuffing propagation of heavily loaded lubricated friction pair elements coated with low-friction WC/C coating for various material combinations...
