| 目的 研究BN-1超高吸收导电消光镀层(简称BN-1镀层)的微观结构、导电消光性能以及空间辐照环境对BN-1镀层消光性能的影响，以考核该镀层是否满足空间光学构件的长寿命使用需求。方法 首先对BN-1镀层进行微观形貌、元素组成、接触电阻、太阳吸收比(αs)的检测，考察镀层的导电性能和消光性能，并对镀层性能的结构基础进行分析。再分别对BN-1镀层进行总剂量为2×1021 atoms/cm2的原子氧辐照以及总剂量为5000 ESH的真空-紫外辐照试验，通过试验结果分析空间模拟辐照环境对BN-1镀层αs的影响规律，研究BN-1镀层的耐空间环境稳定性。结果 BN-1镀层表面具有微纳尺度的绒毛状光陷阱结构，从而具备优异的导电消光性能，镀层接触电阻<5 mΩ，αs>0.98。原子氧暴露后，BN-1镀层αs降低了0.0049，变化值小于0.01，具备良好的耐原子阳光辐照性能。真空-紫外辐照后，BN-1镀层αs增加了0.0009，变化值小于0.01，具有良好的耐真空-紫外辐照能力。结论 BN-1镀层的导电消光性能优异，经历原子氧、真空-紫外模拟辐照后，BN-1镀层αs变化较小，具有较好的耐空间辐照性能，可以满足星敏感器、空间相机等空间光学构件的长寿命服役需求。 |

| The microstructure, conductivity and absorptivity of an ultra-high absorption conductive matting coating (BN-1 coating) and the influence of space irradiation environment on it were studied to evaluate whether the coating meet the requirements of long-life space optical component. Firstly, the micro morphology, element composition, contact resistance, solar absorption ratio (αs) of the BN-1 coating were tested to investigate the conductivity and extinction properties of the coating. The structural basis of the coating extinction performance was analyzed on this basis. Then, the BN-1 coating was irradiated with atomic oxygen dose of 2.0×1021 atoms/cm2 and vacuum-ultraviolet dose of 5000 ESH respectively. The effect of space simulated irradiation environment on BN-1 coating is analyzed through the test results and the stability of BN-1 coating against space environment was studied. Micro-nanometer holes are evenly distributed on the surface of the BN-1 coating which was called light trap structure, leading to the excellent conductivity and absorptivity of the BN-1 coating. The contact resistance is less than 5 mΩ, and the solar absorption ratio (αs) is greater than 0.98. After AO exposure, the solar absorption ratio (αs) of the BN-1 coating decreased by 0.0049 and the change value is less than 0.01. It has good resistance to atomic sunlight irradiation. After VUV irradiation, the solar absorption ratio (αs) of the BN-1 coating increased by 0.0009 and the change value was less than 0.01. It has good resistance to vacuum ultraviolet radiation. BN-1 coating has excellent conductivity and extinction performance. After AO and VUV simulated irradiation, BN-1 coating αs change is small and has good space irradiation resistance, which can meet the long-life service requirements of space optical components such as star sensor and space camera. |
