摘要：
Spectrally selective TiAl/TiAlN/TiAlON/TiAlO coating was deposited on stainless steel and copper substrates using a multiarc ion plating system.The structure,morphology,optical reflectance and electrical resistivity were investigated by X-ray diffraction(XRD),scanning electron microscopy(SEM),spectrophotometer and four-point probe meter,respectively.The results show that the coating exhibits high absorptance(―0.9) and low emittance(0.09―0.19).The coating remains stable in air up to 650℃ for 1h.These properties are of extraordinary interest in solar thermal power generations and energy saving buildings.
