| 摘 要： | 采用等离子喷涂法制备了黑铬太阳能选择性吸收涂层,采用XRD、SEM等测试方法对涂层的物相、微观结构、太阳能吸收性能进行了表征。对涂层进行了打磨,并在涂层表面制备SnO2选择性透过薄膜。研究表明,采用等离子喷涂方法制备的黑铬涂层吸收率为0.93,发射率为0.88,经打磨处理后,发射率降至0.76。添加SnO2薄膜后,涂层吸收率变化小,发射率降至0.50。热震实验表明该涂层具备良好的抗热震性能。 |

| Abstract: | Black chrome solar selective absorbing coatings were prepared by plasma spraying,the coatings′ composition,microstructure,solar absorption properties were characterized with several analysis methods(XRD,SEM).The coatings were polished and deposited SnO2 films by sol-gel process.Researches indicate that the solar absorptance(α) and thermal emittance(ε) of the coatings are α=0.93 and ε=0.88.After being polished,the thermal emittance of the coatings decrease to 0.76.The absorptance changes little but the emittance decreases to 0.50 after SnO2 films are fabricated.The thermal shock test shows the coatings have excellent thermal stability and thermal erosion resistance. |
