In the past decades, Ionic Liquids (ILs) have arisen as environmentally friendly...

... to tribological problems between the bearing surfaces. Adding textures to the surfaces in contact has garnered increased attention in the tribological community as a method to reduce friction and wear of bearing surfaces. Intentionally created dimples on either or both contacting surfaces can serve as lubricant...

... Abstract Friction and wear are inherent problems in mechanical systems, leading to about 23% world’s total energy usage. However, energy losses could be reduced by up to 40% using high-performance lubricants. In order to meet these objectives, Ionic liquids have been studied for more than two...

... behaviors of different lubricants on textured surfaces were then examined based on contact angle measurement. All the frictional tests were carried out on the ball-on-flat reciprocating tribometer under the same working conditions. Lastly, the surface morphology of the wear tracks on Ti6Al4V and tungsten...

... Abstract Wearing cardiac lead implanted may result in various failures, including in-appropriate or missing treatments. Contacts are used on the lateral and radial link in the multi-layered (1 + 6 + 12) pacemaker lead cable. The effect of the coupling mode, however, is not the same as it does...

... friction stir processing (FSP) is studied as well. Coefficient of friction and wear loss characteristics in aspect of the tribological life of the composites developed is compared with the existing automobile brake pad components and found that FSP on composites served the purpose of the materials used...

... Abstract Around 23% of the world’s energy consumption results from rubbing contacts, in which 20% is used to overcome friction and 3% is due to wear and the consequent failure. The implementation of lubricants and effective lubricant additives are indispensable to reduce friction and wear...

... and the associated effects. Recently, ionic liquids have shown a great potential in reducing the friction and wear of materials in contact.
