Abstract

Aging (under heating in air at 100°C ) of Cu and Cu - Cr coatings on glass substrates has been studied by measuring the spectral transmittance and reflectance in the wavelength range 0,4 - 25pm. The results show a fast oxidation of copper films. In the case of Cu-Cr double layer system an initial increase of the IR reflectance has been observed. After this stage the system shows a selectivity similar to that of a single as-received Cu films and very good stability to the oxidation. The prolonged heating (up to 600 h) in air at 100°C does not essentially change the IR reflectance of the Cu - Cr system. The increase of the IR reflectance of Cu - Cr coatings in the initial stage of heating and their further stability has been explained, supposing an oxidation of the Cr layer.
