| 摘 要： | 目的通过直流反应磁控溅射系统在304不锈钢基体上成功制备了含铁类金刚石薄膜,并研究该含铁类金刚石薄膜的润湿性及抗腐蚀行为。方法通过扫描电镜、拉曼光谱仪、原子力显微镜,分别对含铁类金刚石薄膜的结构和形貌进行分析,利用静态接触角测量分析了所制备薄膜的润湿性,且采用动电位极化对有无薄膜沉积的不锈钢体系进行了腐蚀行为测试。结果所制备薄膜具有典型的类金刚石的非晶结构。随着制备过程中甲烷流量的减小,薄膜中sp~3碳含量降低,薄膜致密度逐渐降低。随着甲烷流量的降低,薄膜表面的疏水性能逐渐减小,且自腐蚀电位向负向偏移,腐蚀电流密度逐渐增大。结论含铁类金刚石薄膜能明显提高不锈钢表面的疏水性能和抗腐蚀性能。

| Abstract: | Objective Diamond-like films containing iron (Fe-DLC) were deposited on 304 stainless steel substrates by DC reactive magnetron sputtering. Methods The structure and morphology of the Fe-DLC films were characterized by SEM, Raman and AFM, respectively. The wettability of the Fe-DLC films was examined by the contact angle measurement, and the corrosion resistance in 3.5 wt% NaCl solution of the Fe-DLC films and the uncoated Fe-DLC sample was evaluated by means of potentiodynamic polarization techniques. Results The results show that the as-deposited Fe-DLC films have typical diamond-like characteristics and the methane flow rate in the process of preparation strongly affects the morphology and structure of the films. The sp3 carbon content and compactness of the Fe-DLC films decreases gradually with decreasing methane flow rate. The water-contact angle of the films decreased and free corrosion potentials shifted to more negative values with decreasing methane flow rate, while the corrosion current density increased. Conclusion The hydrophobic property and corrosion resistance performance of 304 stainless steel increase after coating diamond-like carbon films containing iron. |
