Abstract

A porous CeO ₂ coating was prepared by electron beam physical vapor deposition technique. The microstructure and infrared spectral emissivity in wavelength range 2.5∼25 μm were investigated. The surface morphology could be tuned by deposition power density. The as-deposited coating shows (311)-preferred orientation. The great enhancement of infrared spectral emissivity in the whole wavelength range was observed in the porous CeO ₂ coating, compared to a dense CeO ₂ coating. The porous surface structure provides multiple reflection and absorption, thus improves the spectral emissivity. Moreover, the CeO ₂ coating also shows excellent adhesion property to nickel-based alloy substrate. These results show a potential application at high temperature.
