Assessment of the Lubricity of Grease‐Sealing Rotary Shaft Seals Based on Grease Properties

Chemical Engineering &Technology, Volume 46, Issue 1, Page 53-60, January 2023., 2023
Grease‐lubricated rotary shaft sealing systems have an increased risk of starved lubrication. For this work, the lubricity of 23 greases was first evaluated and then correlated with grease properties. The results show which properties correlate with the lubricity of the greases and how the lubricity of the grease can be predicted on the basis of short ...

Geometrical and physical models of abrasion [PDF]

arXiv, 2013
We extend the geometrical theory presented in [5] for collisional and frictional particle abrasion to include an independent physical equation for the evolution of mass and volume. We introduce volume weight functions as multipliers of the geometric equations and use these mutipliers to enforce physical volume evolution in the unified equations.

Hydrogel‐Based Smart Materials for Wound Healing and Sensing

Aggregate, EarlyView.
The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.

Extreme High‐Speed Laser Material Application‐Coated Carbide‐Reinforced Control Plates and Conventional Lead‐Based Plates in Axial Piston Machines

Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023
In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...

Localised stress and strain distribution in sliding [PDF]

arXiv
In this paper, we present a comprehensive analysis of the contact mechanics associated with a micron-sized sliding asperity, which plays a crucial role in the abrasive wear processes. Utilising nanoscratch testing, we experimentally investigate the deformation and employ High-Resolution Electron Backscatter Diffraction (HR-EBSD) to characterise the ...
