中文摘要：
光纤腐蚀传感器具有径细、质轻、抗强电磁干扰、耐高温、集信息传输与传感于一体、易集成于结构内部等一系列优点，在金属腐蚀监测方面的应用研究越来越受到重视．Rutherford等针对飞机上铝材缝隙腐蚀监测问题，提出了一种新的光波导腐蚀传感方案，即用气相物理沉积法（PVD）在光纤纤芯表面上沉积一层Al膜以形成光纤的金属包层，构成了一种能监测Al材腐蚀的光纤传感器；
英文摘要：
In this paper, with the technology of vacuum sputter, pure aluminum corrosion sensitive film was directly deposited on the core of optical fiber with its clad removed. Metallographic microscope and scanning electron microscope （SEM） were used to analyze the structure of the film. The thickness of the pure aluminum corrosion sensitive film was about 14. bonded with the fiber core. Galvanostatic step and 65/μm, and the film was distributed evenly and firmly electrochemical impedance spectroscopy （EIS） were used to evaluate the corrosion resistance in NaCI solution with different concentrations （0.001-0.1 mol·L 1）. The result showed that the corrosion resistance of the aluminum film was similar to that of industrial pure aluminum in NaCI solution with the concentration less than 0.1 mol·L^-1. But the EIS data showed that there were holes on the film surface.
