...Vikram Kumar; Sujeet Kumar Sinha; Avinash Kumar Agarwal The main objective of this investigation is the evaluation of the performance of hard diamond-like-carbon (DLC) or tungsten carbide (WC) and soft (epoxy composite) dual-coatings on the internal combustion (IC) engine piston rings...

... desorption diamond-like carbon friction hydrogen thin films gas-surface interactions humidity DLC environment ultra low friction adsorption Diamondlike carbon (DLC) films are of interest in tribology as solid lubricant coatings for sliding interfaces. DLC films can be made by plasma...

...Said Jahanmir; Hooshang Heshmat; Crystal Heshmat Diamondlike carbon (DLC) coatings, particularly in the hydrogenated form, provide extremely low coefficients of friction in concentrated contacts. The objective of this investigation was to evaluate the performance of DLC coatings for potential...
