2nd Int. workshop “Superlubricity in the automotive real world”
The “superlubricity” phenomenon (SL for short), lubricant regimes when friction coefficient vanishes to ultra-low values, is one of the main current paths to reduce friction. After the success of the 1st workshop in 2015 [see http://www.lfs.usp.br/superlubricity2015], new scientific insights and industrial applications have raised. To mention just a few: new mechanisms for SL on carbon based coatings were proposed; SAE 0W-8 oils entered in production; SL was experimentally verified with coatings other than DLC on actual piston rings and formulated oils; mirror-like and laser textured cylinder bores are being used on both SI and CI engines. However, more fundamental and technological knowledge is still needed to fully understand the complex SL phenomenon. To obtain the SL benefits in terms of wear and fuel savings, a synergic study on lube additives, component coatings and surface finish is necessary.
The two-day workshop will discuss state of art academic and industrial research in the fields of “surface functionalization” and “super-lubricity”. More specifically the workshop will discuss synergic solutions (coating, lube additive, surface finish) that can lead to very low friction under the lubricated regimes found on automotive applications.
