本文叙述在100Kev能量下,以1—6×10~(17)/cm~2的不同剂量对GCr15钢进行了单纯N_2~+注入和轰击扩散镀铬层注入以实现离子束混合。结果表明:注入样品表面显微硬度均有不同程度的提高,其相对最大提高量为340.9％;定性地表明了抗腐蚀性能有所增强;俄歇电子能谱(AES)分析得出了一些有趣的结果。如注入后样品表面含氧量均大幅度降低;钢中含氮量存在一个极值浓度;在高剂量注入下,表面镀铬层与基体材料获得了较好的混合等。最后进行了一些讨论与分析。
This paper describes the pure N 2 + implantation and bombardment diffusion GCr15 implantation at different doses of 1-6 × 10 ~ (17) / cm ~ 2 under 100Kev energy to achieve ion beam mixing. The results show that the microhardness of the surface of the sample increases to some extent with the relative maximum increase of 340.9%. The qualitative analysis shows that the corrosion resistance is enhanced. The analysis by Auger electron spectroscopy (AES) the result of. For example, the oxygen content on the surface of the sample after injection decreased greatly; the content of nitrogen in the steel has an extreme concentration; under the high dose injection, the surface chrome plating layer and the matrix material get better mixing. Finally, some discussion and analysis.
