Investigating the Effect of Water Contamination on Gearbox Lubrication based on Motor Control Data from a Sensorless Drive [PDF]
, 2014 Water is one of the most significant destructive contaminations to lubricants which in turn lead to more power consumption and early damage to rotating machines.

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Biomimetic water-based lubrication: an exploration into vesicle lubrication
, 2023 The replacement of oil-based lubricants with water-based lubricants has been a desirable yet unrealised ambition in Tribology. The use of bio-lubricants has been previously explored; however limited advances have been achieved. Most work has focused on traditional mechanisms, with biomolecules being used to form friction reducing surface films. However,

Elastocapillary Levelling of Thin Viscous Films on Soft Substrates [PDF]
, 2017 A thin liquid film with non-zero curvature at its free surface spontaneously flows to reach a flat configuration, a process driven by Laplace pressure gradients and resisted by the liquid's viscosity.

Advanced Engineering Materials, EarlyView.Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Friction of Si3N4 Ball / Si3N4 Disk Sliding in Water with SiO2 Nano-particles
Tribology Online, 2006 Silica nano-particles that have the average diameter of 7 nm were added to water, and their effects on friction were studied for Si3N4 self-mated sliding couples by a ball-on-disk tribotester under boundary lubricated conditions. By adding 0.01 or 0.1 wt

Effect of Groove Structure on Lubrication Performance of Water-Lubricated Stern Tube Bearings
Lubricants, 2023 This study investigated the lubrication characteristics (i.e., the groove ratio and width) of water-lubricated stern tube bearings, based on the flexibility matrix method and lubrication theory.

Evaporation of a thin film: diffusion of the vapour and Marangoni instabilities [PDF]
, 2004 The stability of an evaporating thin liquid film on a solid substrate is investigated within lubrication theory. The heat flux due to evaporation induces thermal gradients; the generated Marangoni stresses are accounted for.
