| Abstract: | Plasma source ion implantation is a new non-line of sight ion implantation technique for surface modification of materials. For proving scientifically the surface modification effect of this technique and so providing the objective test proofs for the popularization of this technique. This technique was used for modification of Ti6A14V alloy with nitrogen ions. The concentration, microstructure and properties of the implanted layer were analyzed. The results show that the distribution of the nitrogen concentration in the implanted layer has the like Gauss, titanium nitride and amorphous phase have formed in the implanted layer, and the microhardness and friction properties are improved obviously. |
