Thermal application Description
Thermal conduction
Thermal spray coating systems can promote thermal conductivity. Thermal sprayed copper and thermal sprayed aluminum are some examples of a thermally conductive surface. These coatings can not only promote heat transfer, but can evenly distribute the heat for even greater efficiency.
Thermal barrier
Thermally barrier coatings are designed to slow heat transfer and insulate the substrate. The coating systems used today usually consist of two components: a metallic bond coat (usually an MCrAlY) that also acts as an oxidation resistant layer and a top coat of ceramic (usually a yttrium stabilized zirconium oxide). The coating system has a low rate of thermal conductivity and a high thermal expansion coefficient. These coating systems extend the service life of components or allow components to operate at higher temperatures, increasing thermal efficiency.
