摘　　要：采用电镀方法在预镀银H85铜合金表面电化学沉积黑镍涂层,制备出了太阳能选择性吸收涂层。研究了电镀时间、电流密度以及光亮银底层等参数对涂层整体的太阳能吸收率α、发射率ε的影响,采用SEM、EDS、XRD以及光谱选择性(α/ε)等方法对涂层进行了表征,得到了制备黑镍太阳能选择性吸收涂层的优化工艺。实验结果表明,黑镍涂层主要相结构为N-Diamond C、NiO、NiC、NiZn3;添加光亮银红外反射层能较为明显地改善涂层的选择性吸收性能;获得了α=0.90,ε=0.06,α/ε=15的太阳能选择性吸收涂层。The black nickel solar selective coating was prepared on the pre-silver-plated H85 copper alloy by plating method.The effect of plating time,current density and bright silver bottom-coating＇s presence or absence were studied on the coating＇s solar absorptance.This coating was characterized by surface SEM EDS,XRD phase structure and the solar selectivity（α/ε） and a reasonable process parameters of black nickel selective absorbing coating was proposed.The result shows that the structure of the coating consists of N-Diamond C,NiO,NiC,NiZn3;the addition of the bright infrared reflection layer of silver got a significant improvement on the coating＇s selectivity and finally a fine selective coating was obtained（α= 0.90,ε=0.06,α/ε=15）.
