The purpose of the present work is to obtain fundamental data for introducing ion engineering techniques in dental alloys. Ion implantation, plating and mixing techniques were employed. Ion implantation improved remarkably the corrosion resistance. A superlattice structure was formed by annealing after the implantation. However, it is a problem for the implantation surface to have rough surface. Ion plating produced a homogeneous coating surface and improved the strength and corrosion resistance. We got best results by ion mixing technique, which corresponds to use at the same time ion implantation and ion plating. This method has an additional merit which we can control the thickness of surface modification. During the present work, we also discuss the ordering mechanism in CuAu I,the formation of which is expected by annealing after the surface modification in dental gold alloy. The ordering proceeded in three stages (I,II and III). Stage I corresponds to the ordering by migration and annihilation of quenched-in excess divacancies. This ordering stage will be available on ion mixing treatment sample, because of be possible at room temperature.

本工作的目的是为在牙科合金中引入离子工程技术获得基础数据。采用离子注入、电镀和混合技术。离子注入显著提高了膜层的耐蚀性。注入后退火形成超晶格结构。然而，植入表面具有粗糙表面是一个问题。离子镀可获得均匀的镀层表面，提高镀层的强度和耐蚀性。采用离子混合技术，可以同时进行离子注入和离子镀，获得最佳的效果。这种方法的另一个优点是可以控制表面改性的厚度。在目前的工作中，我们还讨论了CuAu I的有序机制，预期在牙科金合金表面改性后通过退火形成。该命令进行了三个阶段（一，二和三）。第一阶段对应于淬火过剩双空位的迁移和湮灭的顺序。由于可以在室温下进行离子混合处理，因此这种排序阶段将可用于样品。
