Special Issue Information

Dear Colleagues,

During the last three decades, carbon-based coatings have enjoyed a growing interest in several industrial applications. By tuning the carbon sp3-to-sp2 bonding ratio and by alloying the carbon with other elements, the researchers have been able to tailor unique physical, mechanical, and tribological properties in order to satisfy an increased technological demand. Nitrogen doping and other alloying additions like metals, boron, silicon, phosphorous, fluorine, etc., have also been developed to improve their mechanical and tribological properties.

Already in the 1990’s, carbon-based coatings enabled the operation of fuel injectors in gasoline and diesel engines, providing necessary protection against wear, scuffing and other adverse effects of lubricant-lean friction. Nowadays, carbon-based coatings are found in most facets of our daily lives, from the protective films on the hard disks of computers to the lubricious coatings on the blades of a disposable shaving machine. They are used in the chemical, food and packaging industries (valves and cutting hardware), semiconductor processing equipment (wafer handling and mechanical drives of cluster tools), compressors and pumps, and automotive industry (piston rings, camshafts, gears), biomedical applications (stents, heart valves, chirurgical instruments), etc. All the emerging applications of carbon-based coatings are originated in the great variety of crystalline and disordered structures that are possible to obtain by many different deposition techniques.

In this special issue we are requesting original contributions from academic or industrial researchers working on theoretical and/or experimental aspects concerning all kind of carbon-based coatings with improved tribological properties, from basic research to applied (tribological) uses.

The role of surface protective additives becomes vital when operating conditions become severe and moving components operate in a boundary lubrication regime. After protecting film is slowly removed by rubbing, it can regenerate through the tribochemical reaction of the additives at the contact. However, there are limitations about the regeneration of the protecting film when additives are totally consumed. On the other hand, there are a lot of hard coatings to protect the steel surface from wear. These can enable the functioning of tribological systems, even in adverse lubrication conditions. However, hard coatings usually make the friction coefficient higher, because of their high interfacial shear strength. Amongst hard coatings, diamond-like carbon (DLC) is widely used, because of its relatively low friction and superior wear resistance. In practice, conventional lubricants that are essentially formulated for a steel/steel surface are still used for lubricating machine component surfaces provided with protective coatings, such as DLCs, despite the fact that the surface properties of coatings are quite different from those of steel. It is therefore important that the design of additive molecules and their interaction with coatings should be re-considered. The main aim of this paper is to discuss the DLC and the additive combination that enable tribofilm formation and effective lubrication of tribological systems. Full article
