为了实现在金属基体上电沉积类金刚石薄膜的三维沉积，选择不同尺寸的不锈钢基体作为电沉积阴极。利用X射线光电子显微镜、拉曼光谱和扫描电子显微镜（SEM）对薄膜的化学成分、微观结构和表面形貌进行了表征。结果表明，对于尺寸大于阳极的不锈钢，DLC膜只能沉积在面对阳极的表面上，而对于尺寸小于阳极的不锈钢，DLC膜可以沉积在基底的两个表面上。进一步的研究表明，在两个表面上的膜显示出相似的微观结构和形貌。利用准静电场理论对实验结果进行了讨论，提出垂直于基体表面的电场分量的存在是类金刚石薄膜电沉积的前提。研究结果为进一步实现在复杂形状导电基体上三维沉积类金刚石薄膜提供了理论依据。© 2016，Materials Review杂志。All right reserved.
To accomplish three-dimensional deposition of diamond-like carbon (DLC) films on metal substrates by electrodeposition, stainless steel substrates with various sizes were selected as cathode for electrodeposition. The chemical composition, microstructure, and surface morphologies of the films on both surfaces of the substrates were characterized by X-ray photoelectron microscopy, Raman spectroscopy and scanning electron microscope (SEM). Results indicated that for the stainless steel with a larger size than anode, the DLC film can be deposited on the surface facing the anode only, but for the stainless steel with a smaller size than anode, the DLC films can be deposited on both surfaces of the substrates. Further investigations revealed that the films on both surfaces show similar microstructures and morphologies. The quasi-static electric field theory was utilized to discuss the experimental results, proposing that the existence of electric field component vertical to substrate surface is the prerequisite of the electrodeposition of the DLC films. The results furnish theorial foundation for the further realization of three-dimensional deposition of DLC films on conductive substrates with complex shapes. © 2016, Materials Review Magazine.
