| 摘 要： | 利用脉冲激光沉积结合计算机辅助衬底扫描技术制备了尺寸为70×66mm、均匀性为±5%的类金刚石薄膜,薄膜显微硬度最高为27GPa,薄膜结合强度达到20000转;在制备大尺寸薄膜的过程中,衬底扫描速度越慢,薄膜的均匀性越好;在应用传统清洗等方法的基础上,认为增大镀膜粒子的能量对于提高薄膜和衬底的结合强度是非常重要的.

| Abstract: | In this work,large area uniform hydrogen free DLC films have been deposited at room temperature by krf pulsed laser ablation with computer aidded substrate scanning under high vacuum condition.The films exhibited a thickness variation less than?5%within the area of 70?66mm.Properties of the film obtained have been analyzed.In discussion,scanning speed of the substrate is believed to be the most important factor with the uniformity of the film.As for adhesion strength of DLC films,the energy of the particles deposited on the substrate is supposed to be the most important factor in addition to routine treatment. |
