摘要
采用微波等离子体化学气相沉积(MPCVD)方法在铜衬底上沉积了微米和纳米两种金刚石薄膜,过渡层均为钛-铝-钼。用场发射扫描电子显微镜(FESEM)观察薄膜的表面及断面形貌,用拉曼(Raman)光谱测量所得金刚石薄膜的质量,利用压痕法测试了所得薄膜的附着性能,研究结果表明:过渡层可有效提高微米金刚石薄膜在铜衬底上的附着力,反应气氛中Ar的存在可促使纳米金刚石薄膜的形成,改善薄膜表面的粗糙度。
Micro/nano diamond films were prepared by microwave plasma chemical vapor deposition(MPCVD) on Cu substrate with Ti-Al-Mo as an interlayer.The surface and cross-section morphologies were observed by FESEM, and Raman spectroscopy was used to analyze the as-deposited diamond films. The adhesion between substrate and as-deposited film was examined by way of indentation, and the results showed that the Ti-Al-Mo interlayer can enhance the adhesion effectively. In addition, the Ar gas in reaction atomosphere can accelerate the formation of nanofilms, thus improving the film surface roughness.
