Abstract

A series of AlCrNO based solar selective absorber coatings were deposited by cathodic arc ion plating on three kinds of different infrared reflectors (AlCr, Cu, Cr) and with different deposition currents respectively. The surface morphology, phase structure and surface roughness were characterized by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and roughmeter respectively. The results show that the AlCr-AlCrNO based coating exhibited a high absorptance of 0.91 and an emittance of 0.52 when AlCr was served as infrared reflector. Meanwhile, a higher absorptance ( =0.92) of AlCr-AlCrNO based coating was obtained when varying deposition current from 50 A to 60 A. Moreover, the roughness is one of impacts on the emittance. Increasing the deposition current to 70 A brings about the raising of the roughness, increasing the emittance therefore.
