摘　　要：为研究增透膜的热带海洋环境适应能力及防水层对膜层的保护作用,将镀有防水层和未镀防水层的两类锗镀红外增透膜样品投放于热带海洋环境中进行棚下自然暴露试验,以3个月为一个周期,共试验4个周期。通过对各周期试验样品的形貌、结构、成分及透过率进行观察和检测,分析其失效模式、损伤过程和透过率变化规律。试验结果显示,在棚下试验一个周期,膜层均未发生损伤;两个周期后,膜层边缘位置出现点蚀现象,且腐蚀程度随试验时间的增加而变得严重,并由样品边缘向中心逐渐延伸;试验4个周期后,表面未镀防水层样品边缘腐蚀较为严重,镀防水层样品腐蚀较轻,在3.7~4.8μm波段的透过率未出现明显衰减,表现出更好的热带海洋环境适应性。To study the adaptability of anti-reflection film in tropical marine environments and the protective effect of a waterproof layer on the film,two kinds of germanium-coated infrared antireflection film samples,with and without a waterproofing layer,were put into a tropical marine environment for natural exposure test under the shed.By observing and detecting the morphology,structure,composition,and transmittance of each cycle test sample,the failure mode,damage process,and change in transmittance were analyzed.The results show that the membrane was not damaged during one cycle under the shed.After two cycles,pitting occurred at the edge of the film layer,and the degree of corrosion became severe with an increase in test time,gradually extending from the edge to the center of the sample.After four test cycles,the edge corrosion of the samples without the waterproofing layer was more severe,and the corrosion of the samples with the waterproofing layer was lighter.The transmittance of the samples at 3.7-4.8μm did not decrease,showing better adaptability to the tropical marine environment.
