摘要
大剂量Ｔｉ＋、Ｃ＋和Ｔｉ＋＋Ｃ＋注入Ｈ１３钢可使注入层硬度和抗磨损寿命明显增加，尤以Ｔｉ＋＋Ｃ＋双注入效果最佳．实验结果表明注入的Ｔｉ和Ｃ原子浓度可分别达到２２％和４５％；超饱和Ｔｉ和Ｃ浓度形成了固溶强化；注入层中已形成弥散的硬化相，如Ｆｅ２Ｔｉ、ＴｉＣ、Ｆｅ２Ｃ和Ｆｅ５Ｃ２等，出现了弥散强化效果．注入层表面形成了一层２０ｎｍ厚的薄碳层，使之呈现出自滑润特性。
Obvious increase of hardness and wear lifetime has been observed for high dose pulse Ti,C and Ti+ C dual implanted H13 steel.The Ti+ C dual implantation is better than implantation with other ions.It is shown that the implanted Ti and C concentration can reach 22% and 45% respectively,the over-saturated solid solution of C and Ti appeares,and hardening of solid solution is formed in the implanted layer. The dispersive hardening phases such as Fe2C3,Fe5C2,Fe2Ti and TiC are formed. There is a thin carbon film on the surface of Anplanted layer,increasing surface lubrication.
