【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 by DC reactive magnetron sputtering system on 304 stainless steel was successfully prepared iron containing DLC films, and Study on the wettability and corrosion behavior of the iron containing DLC films. Methods by scanning electron microscopy, Raman spectroscopy, atomic force microscopy, respectively. The structure and morphology of iron containing DLC films was analyzed. Analysis of the wettability of the film by static contact angle measurement, and potentiodynamic polarization of a thin film deposition system for the corrosion behavior of stainless steel test. The amorphous structure of the films with results of typical gold diamond. With the decrease of the preparation of methane flow in the process of reducing carbon content sp~3 in the film, the film density decreased gradually. With the decrease of methane flow, the hydrophobic properties of the film surface decreases gradually, and the corrosion potential of negative migration, the corrosion current density increases gradually. Conclusion the diamond like diamond films can obviously improve the hydrophobicity and corrosion resistance of the stainless steel surface.
