The Mechanism of Fructose Hydrogenation on Activated Base Metal Surfaces

The effects of water environment such as temperature and dissolved ions on tribological properties of DLC against brass were studied for development of the water-lubricated hydraulics, valves and cylinders based on metal. A ball-on-disk type rotating tribotester was used for detailed examination of above mentioned factors. DLC was deposited on the disk by the unbalanced magnetron spattering system. Pure water and quasi-tap water were used to study the effects of dissolved ions. The results show that temperature and dissolved ions have major impact on the wear of DLC. EPMA, XPS and AES indicate that tribo-layer on the metal surfaces, consists of carbon and the base metal and some element from water, plays important role for the phenomena.

White Metal

Silver has generally been valued second only to gold from at least as early as 2000BC. A material which is highly prized becomes a status symbol and cheaper imitations find a ready market. Craftsmen very early developed methods of applying thin layers of silver onto base metal as an economical use of precious metal, whether for its decorative effect or, particularly in the case of plated coins, to deceive the customer. Unfortunately, silver plating is less commonly preserved than gold plating, and corrosion at the interface between the silver and base metal may destroy the evidence of how the plating was applied. The situation is complicated because many of the white metal surfaces on pieces labelled as ‘silvered’ are in fact produced by tin, or more rarely, by arsenic. Nevertheless, there are still sufficient surviving examples to indicate that silver plating has a long history during which techniques were developed to give better results and to allow more economical use of the precious metal.
