摘　　要：本研究以Fe-20Cr不锈钢为对象,采用磁控溅射技术制备纳米涂层,用多种配比的酸性腐蚀溶液侵蚀Fe-20Cr纳米涂层样本,样本表层产生钝化膜,利用Mott-Schottky曲线分析钝化膜半导体特性,发现纳米涂层被侵蚀后产生的钝化膜为n型半导体。This research targets Fe-20 Cr stainless steel.It uses nano coating which is prepared by magnetron sputtering and the acidic etching solution with various proportions to erode Fe-20 Cr nano coating samples.Then the surfaces of these samples produce passive film.The research will analyze the characteristics of the passive film semiconductor through curve analysis.Then it finds the passive film after erosion is N type semiconductor.

关 键 词：磁控溅射 钝化膜 Mott-Schottky曲线 N型半导体
