come fare opzioni binarie 60 secondi Superhard and slick coatings can improve the performance of all kinds of moving mechanical systems, including engines. Friction, wear, and lubrication strongly affect the energy efficiency, durability, and environmental compatibility of such systems. As an example, frictional losses in an engine may account for 10-20 percent of the total fuel energy (depending on the engine size, type, driving conditions, and weather, for example). The amount of emissions produced by these engines is also strongly related to their fuel economy. In general, the higher the fuel economy, the lower the emissions. In fact, achieving higher fuel economy and lower emissions is one of the most important goals for all industrialized nations. SSC with its self-lubricating and low-friction nature can certainly help to increase the fuel economy of future engines.

binär optionen plattformen Scuff-proof, low friction coating delivers as predicted
Wear and scuffing are common causes of catastrophic failure in components frequently exposed to heavy loading, such as earth-moving and mining equipment. A coating that helps reduces material shock would greatly enhance the lifetime of the equipment, which is why nitride, carbide, and diamond-like coatings were developed. A new alternative, Superhard and Slick Coating (SSC) developed by a team of researchers from Argonne National Laboratory, Argonne, Ill., Galleon International Co., Brighton, Mich., and Hauzer Technocoating, Venlo, The Netherlands, differs from these existing coatings in its chemistry, which consists primarily of molybdenum and copper, along with silver, antimony, and tin. It is a designer coating; its composition was predicted by a crystal-chemical model proposed by the coatings developers. In laboratory and engine tests, SSC reduced friction by up to 80% compared to uncoated steel surface and virtually eliminated wear under severe boundary-lubricated sliding regimes. Scuffing was too low in typical testing to be measured by test machines. SSC can be produced at moderate temperatures (200ºC to 400ºC) on almost any kind of metallic substrates at high growth rates and, unlike other physical-vapor-deposited hard coatings, it does not have a columnar morphology.
