Popis:	The paper presents the results on accelerated corrosion/erosion tests, of Thickness Insensitive Spectrally Selective paints, based on alumina matrix infiltrated with inorganic oxide pigments used in the solar-thermal energy conversion. The mechanism of the corrosion/erosion process is presented and discussed based on the polarization Tafel curves obtained in NaCl 3.5% solution. Optical properties (solar absorptance and thermal emittance) were measured before and after the corrosion tests and the results were correlated with the sample’s morphologies and the corrosion parameters. The influence of the antireflection layer on the corrosion resistance and spectral selectivity is also discussed.
