Diamond friction: simulation reveals previously unknown friction mechanisms at the molecular level

http://www.iwm.fraunhofer.de/en/press/press-releases/01_09_17_diamondfrictionunknownmechanisms.html

Diamond coatings help reduce friction and wear on tools, bearings, and seals. Lubricating diamond with water considerably lowers friction. The reasons for this are not yet fully understood. The Fraunhofer Institute for Material Mechanics IWM in Freiburg and the Physics Institute at the University of Freiburg have discovered a new explanation for the friction behavior of diamond surfaces under the influence of water. One major finding: in addition to the known role played by passivation of the surfaces via water-splitting, an aromatic passivation via Pandey reconstruction can occur. The results have been published in the journal Physical Review Letters.

New innovative process improves the adhesion of diamond to cemented carbide

http://www.iwm.fraunhofer.de/en/press/press-releases/31_07_2017_processimprovesadhesionofdiamondtocementedcarbide.html

To reduce process costs in industrial parts manufacturing while simultaneously improving quality, the use of diamond-coated, cemented carbide cutting tools has increased. Adhesion of diamond coatings was previously problematic, particularly when processing composite or lightweight materials. Suitable pretreatment is therefore vital. Dr. Manuel Mee of the Fraunhofer Institute for Mechanics of Materials IWM has developed a new pretreatment routine that increases the adhesion of CVD diamond to carbide: by combining several approaches into a single process, all factors which affect the adhesion of the coating can be taken into consideration, leading to a fundamental improvement of the adhesion.

The principle of #metal #plating is almost identical for all applications. The metal to be plated is dissolved in the electrolyte and the object to be plated is cathodically polarised.
