摘 要: 以目前常见太阳能系统的铝反射镜为研究对象,采用扫描电子显微镜(scanning electron microscopy,SEM)、X射线衍射(X-ray diffraction,XRD)、可见光反射/透射测量仪分析铝反射镜的组织结构,及其与反射率的关系,使用维氏硬度测量、压痕形态金相观察等技术研究反射镜的力学性能。XRD和SEM能谱分析表明:铝反射镜表面为单层或双层保护膜,且为非晶结构。铝膜表面受压力变形和裂纹图像观察证实室外型反射镜具有较高的表面耐磨性能。
关 键 词: 太阳能;铝反射镜;组织结构;反射率

Abstract: In this paper, the microstructures and properties of indoor and outdoor aluminum reflector for concentrated solar system were investigated by means of scanning electron microscopy (SEM), X-ray diffraction (XRD) and UV/VIS reflection/transmission measurement apparatus. The anti-friction and performance of the protective superficial layers of reflector were quantitatively evaluated by HV hardness test and optical observation. The results showed that the surface of aluminum reflector was consisted of single or double protective film with amorphous structure. The pressure distortion and the crack image of aluminum membrane surface proved that outdoor reflector had good superficial wear-resisting performance.
