- The effect of the changes in the micro-geometry in a rolling contact on wear processes like running-in is of great interest.
- A Newton-Raphson scheme is used to solve the transient elastohydrodynamic lubrication line-contact problem with two-sided features and waviness for moderate loads.
- Minimum quantity lubricant milling (MLQM) with nanofluids is one of the main processing methods used in sustainable green manufacturing.
- Galling is the surface phenomenon which involves adhesion of local contact points and creation of protrusions on the juxtaposition of surfaces owing to high friction, inappropriate tribological loading, starved lubrication and high contact pressure (~ 1000 kPa). All these factors result in severe plastic deformation varying from 8000 to 10,000 µε (ε-strain) and diffusion of materials into one another, which consequently results in fatigue wear, surface roughness, tribocorrosion and seizing up of critical parts.
- The surfaces of lubricated mechanical components operating under extreme conditions are protected by films that form in the presence of additives in lubricant formulations.
- When uninsulated pipelines are used to transport crude oils with high wax content (greater than 2 wt %) in cold environments, the pipelines may become plugged with wax gels when a flow shutdown occurs.
- Coalescence effect of the surface disposal devices is greatly impacted by the large amount of aging oil because of its complicated interfacial properties, which heavily affects oil production.
- The assessment of grinding wheel wear behaviour is usually restricted for practical reasons to the measurements of the total reduction in wheel diameter and rarely includes measurements to wheel form and surface microtopography.
- Vegetable oils constitute a potential base stock for bio-lubricants, which has good biodegradability, high flash point, high viscosity index and excellent boundary lubrication properties.
