近十余年来,人们对离子注入在金属中的应用给予愈来愈多的重视。这种技术是否能够在改善工业磨损和腐蚀两大课题中发挥作用,更是大家所关心的问题。离子注入具有任选元素、浓度和深度,易于控制,低温,不改变零件尺寸、形状和光洁度等特点。根据国内外文献报道,经过各种离子注入处理后的不同材料(试样)或零件(工具、刀具、模具)的耐磨性均可得到不同程度的提高。但是,不能令人满意的是注入层厚度往往仅有十分之几微米,这与工业应用中的允许磨损量相差几个数量级。使在考虑推广应用的试验范围受到一定的限制。
For more than ten years, people pay more and more attention to the application of ion implantation in metal. Whether this technology can play a role in improving the two major topics of industrial wear and corrosion is even more a matter of concern. Ion implantation with optional elements, concentration and depth, easy to control, low temperature, does not change the size, shape and finish features. According to the domestic and foreign literature, the abrasion resistance of different materials (samples) or parts (tools, knives, molds) after various ion implantation treatments can be improved to different extents. However, it is unsatisfactory that the thickness of the injection layer is often only a few tenths of a micrometer, which is several orders of magnitude less than the allowable amount of wear in industrial applications. So that in considering the promotion of the scope of the test subject to certain restrictions.
