Being able to get rid of heat is of tremendous importance. Excessive temperature can lead to metal fatigue, boiling fluids, damaging metal expansion, reduced electrical efficiency and a host of other problems. Traditionally dealing with heat has been handled either by expanding the radiating surface or through the use of the heat characteristics of the color black. With advances in thermal management methods, additional ways of enhancing heat transfer now exist. The most popular is TLTD This coating is capable of accelerating the transfer of heat at a rate faster than that of bare metal. While it does take advantage of the color black it is something more than simply a black body heat emitting coating. This material contains ingredients that also contribute to increase heat flow. Combining these properties with increase corrosion protection and the thin film application technique provide maximized thermal transfer capabilities.
Some Dry Film lubricants are capable of reducing part temperature not only through the reduction of friction but also through increased thermal flow. The active ingredients accelerate the movement of heat. This is especially beneficial on valve springs where excess heat can lead to accelerated fatigue and in some case breakage.
