Fabrizio Colombo,Jonathan Gantnericant, providing a fluid layer separating moving surfaces or removing heat and wear particles while keeping friction at a minimum. Many of the properties of the lubricant are enhanced or created by the addition of special chemical additives to the base fluid. For example, stability to oxidation and

Quantum Brownian Motion Revisitedengines with close tolerances between moving parts would not be possible without engine oils containing a tailored package of chemical additives. Progressive advances in additive technology not only allow today’s engines to operate efficiently, but also dramatically increase the engine’s useful life

Quantitative Methods for Managementcal components and ‘additive packages’ which contain a specially developed blend of these components. Chemical companies produce polymers which help to maintain the viscosity of the oil at elevated temperatures. Sometimes two or three of the above are produced by the same company. The information on

Quantitative Methods for Managementes. With respect to the properties, one can say that industrial lubricants involve all classes of lubricants applied in practice. They include gases (mostly air), various kinds of liquid products (mineral oils, animal and vegetable oils, synthetic oils, water based fluids, etc.), greases (simple soa
