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 14.65 μm, and the film was distributed evenly and firmly bonded with the fiber core.Galvanostatic step and electrochemical impedance spectroscopy (EIS) were used to evaluate the corrosion resistance in NaCl 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 NaCl solution with the concentration less than 0.1 mol·L -1.But the EIS data showed that there were holes on the film surface.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.
