摘要：

Spectrally selective AlCr-AlCrON cermet solar absorber coating has been deposited on Cu substrate experimentally by reactive DC magnetron sputtering and heat-treated in air at 300 degrees C for 2h. The spectral properties and thermal stability of the as-synthesized AlCr-AlCrON coatings were characterized. The solar absorptance and thermal emittance of the as-synthesized AlCr-AlCrON coating are 0.926 and 0.065, respectively. In addition, after heat treatment at 300 degrees C for 500 h in air, the spectral properties of the as-synthesized AlCr-AlCrON coating is virtually unchanged. The results indicate that the as-synthesized AlCr-AlCrON coating has good spectral properties and thermal stability, which will be a good selective absorbing coating for mid-temperature solar vacuum collector tubes.
