Knowing A Bit More About Functions Of Graphite Lubricant: Ideal Lubricant To Decrease Friction In Various Purposes
Graphite is a form of carbon, which is silvery black in colour. Graphite is one of the popular materials used as solid lubricant. The lamellar structure of graphite (the nature to flake), in the form of dry powder, makes it perfect to reduce friction. Graphite can also work as a liquid based lubricant. The lubrication film provides resistance to wear and tear and also seizure resistance.
As a dry lubricant, the powdered graphite reacts with water vapour and the molecular bonding doesn't occur, leaving it dry and slippery. But, it does not bond well with the surface and thus keeps falling off, increasing the need to be applied often. Solid graphite lubricant is tolerant to temps of about 900 degree F. Higher temperatures than this causes oxidation of graphite.
The liquid graphite lubricant is of different types. The graphite grease is designed to attach to the surface, where the grease will stop the graphite from falling off the work surface. Another combination of graphite lubricants with liquid base is such that the liquid will evaporate when the mixture is painted on the surface, leaving the graphite to work to decrease friction.
As a dry lubricant, graphite can be used in certain situations where wet lubricants may cause danger as in electric fittings or when lubricating substances such as wood. Also, graphite grease can tolerate more heat than standard grease or other lubricants.
Graphite may be used as an additive in lubricating oil to increase the thermal tolerance. They are also used as ingredient of polymer based compound anti-friction coatings and form the second phase particles of metal based composite anti-friction coatings. They are used as molds for continual casting and solid lubricant in metal forming.
Graphite is also used in continuous casting molds. The molds are fabricated from iso-statically pressed graphite. The low friction between the mold surface and solidifying metal ensures smooth extraction of the casting. The crystal structure of graphite offers low friction without the necessity of additional lubrication.
Graphite is characterized as natural and artificial. Natural graphite is derived from mining. The refined graphite contains carbon, sulfur, SiO2 and Ash. The crystallizing quality of graphite is determined by the greater content of carbon, and more the lubricity and resistance to oxidation. Synthetic graphite is sintered from high temperature and has very high carbon content of up to 99.5-99.9%, and is therefore extremely good as a lubricant.
While the conventional automotive oils cannot withstand the high temperatures, graphite can function as lubricants in auto engines which reach temperatures as high as 1,250 degree F. The commercially available graphite lubricant is a colloidal dispersion of billions of microscopic particles of graphite. When this is added to the crankcase of an engine, it functions with the motor oil to reduce friction. It also penetrates effectively into areas where oil cannot reach, keeps oil from thickening, enhances compression and aids energy consumption and fuel economy.
