本文主要介绍螺钉、螺帽和钟表零件的离子镀渗铝初步研究成果,讨论了铝膜厚度与极间距离、真空室内压强、工作电压之间的关系;绕镀性与极间距离、工件尺寸之间的关系,从而得出最佳工艺参数。测定了铝膜耐蚀性及疲劳性能。对铝膜进行了x射线结构分析、电子探针分析以及扫描电镜分析。 This paper mainly introduces the preliminary research results of ion plating and aluminizing of screw, nut and watch parts, and discusses the relationship between the thickness of aluminum film and the distance between electrodes, the pressure in the vacuum chamber and the working voltage; the distance between the plating and the electrode, the size of the workpiece The relationship between, so as to draw the best process parameters. The corrosion resistance and fatigue property of aluminum film were measured. The aluminum film was analyzed by x-ray structure, electron probe analysis and scanning electron microscopy.
