摘要

采用改进的MEVVA源阴极对不锈钢进行了V +C共注入

并做了X射线衍射分析

硬度和磨损实验。V +C共注入剂量为 1× 10 17— 8× 10 17cm- 2

能量为 80keV。实验结果表明

V +C共注入后不锈钢表面的机械性能得到了改善

表面硬度增加了 16%— 82 %

而耐磨性则是未注入样品的 1.4— 2 .2倍

最好的结果均从剂量为 4× 10 17cm- 2 的样品中得到。X射线分析表明

V +C共注入后在不锈钢表面形成了新相FeV

Cr2 VC2

Cr2 3 C6 和Fe5C2 。这些新相在提高表面硬度和耐磨性方面起了重要作用。这些结果与V +C双注入同种不锈钢所得结果进行了比较

比较结果表明共注入方法对材料表面改性比双注入方法更有效。

Abstract

The cathode of MEVVA source was modified and co-implantation of V+C was carried out using the modified cathode at an average energy of 80keV to doses ranging from 1×10 17 to 8×10 17 cm -2 . The experimental result showed that the surface mechanical properties in the co-implanted layer were improved. The surface hardness increased 16 % - 82 %

and the wear resistance was 1.4-2.2 times of that of unimplanting surface. The maximum hardness and wear resistance were obtained from the sample with a dose of 4×10 17 cm -2 . By means of XRD

it was known that intermetallic compounds such as FeV

Cr 2VC 2

Cr 23 C 6

and Fe 5C 2 were formed. These new Phases were contributed to the improvement of the surface properties for implanted layer. These results were also compared with that of V+C dual implantation. It showed that co-implanting method is more effective than dual-implantation for surface modification.
