Magnetron sputtering SiC films on nickel photonic crystals with high emissivity for high temperature applications
Source abstract
Abstract
Abstract High emissivity coatings have been widely used in many high temperature applications. Here we report a novel structure of magnetron sputtering silicon carbide (SiC) films on Ni photonic crystals (PCs) to improve emissivity performance. It is found that SiC coatings reveal two-dimensional patterned structures due to their preferential growth on the skeleton of Ni PCs. The spectral emissivity results show periodic structures and surface-porous structured SiC can enhance the coatings’ spectral emissivity because of higher rough surface, lower reflectivity and magnitude of thermal fluctuations. The method holds promising potential for preparing a series of high emissivity coatings and highly ordered metal–ceramics composites microstructures for thermophotovoltaic (TPV) radiator, pyroelectric and other photonics applications.
