摘要：
A novel four-layered Mo/AlCrON(HMVF)/AlCrNO(LMVF)/AlCrOx tandem coating was designed and fabricated by cathodic arc ion plating for solar-thermal conversion applications. The chemical composition, structures and thermal stability of the coating were systematically investigated by SEM, EPMA, XRD, TEM, XPS and Raman. The optical properties of the as-deposited and annealed coatings were measured by spectrophotometers. The high-temperature emittance of the coating was measured by a steady-state measurement system. Results showed that tandem coating exhibited a high solar absorptance of 0.921, and a low emittance of 0.12 at 25 ?°C, as well as emittance of 0.26-0.35 at temperatures range of 300-519 ?°C. The structure analysis showed that the nano-multilayered structured HMVF and LMVF layers, acting as the main absorber, were consisted of the Cr
