溅射太阳能选择性吸收涂层,应用于太阳能集热器。它是采用单个圆柱(或平板)铝阴极,于氩气中溅射铝膜为底层,先后于氩-氮(或氩-一氧化碳)混合气体与纯氮(纯一氧化碳)中反应溅射成份渐变的铝-氮(或铝-碳-氧)复合吸收材料。涂层的太阳吸收率α
Sputtering solar selective absorption coating, used in solar collectors. It uses a single cylindrical (or flat) aluminum cathode sputtering aluminum film in argon as the underlying, followed by a gradual change in reactive sputtering composition of argon-nitrogen (or argon-carbon monoxide) mixed gas and pure nitrogen Aluminum - nitrogen (or aluminum - carbon - oxygen) composite absorbent material. Solar absorptance of the coating α
