2Cr13钢的全方位离子注入与离子束增强沉积复合表面强化处理

对 2Cr13不锈钢表面进行了等离子体浸没离子注入(PIII)与离子束增强沉积(IBED)复合强化处理。对强化后的试样进行了俄歇电子能谱(AES)、X光电子能谱(XPS)分析及显微硬度、摩擦磨损和耐腐蚀性能测试。结果表明,处理后的试样表面层中含有强化相TiN和CrN;与基体相比,被处理试样的显微硬度显著增大,最大增幅达80 4%;摩擦系数降至 0 2~0 3,磨痕宽度最大减少了近 4倍;腐蚀电位最大提高了 5倍,腐蚀电流密度减少了 26倍。磨损中粘着现象大大减轻,耐磨耐蚀性能得到了显著改善。

Surface Modification of 2Cr13 Steel by Plasma Immersion Ion Implantation Combined with Ion Beam Enhanced Deposition

Surface modification of 2Cr13 stainless steel was carried out using plasma immersion ion implantation (PIII) combined with ion beam enhanced deposition (IBED) technique. The chemical composition, concentration-depth profile of various elements were characterized by Auger Electron Spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). The microhardness, corrosion resistance, friction and wear behavior of the samples were evaluated. The results show that, titanium nitrogen (TiN) and chromium nitrogen (CrN) phase are existed in the surface layer. Compared with the substrate, the microhardness of the treated samples are enhanced significantly, the maximum is increased by 80.4%; friction coefficient is reduced to 0.2~0.3; wear track width and corrosion current density are decreased by 4 times and 26 times, respectively. Corrosion potential is increased by 5 times. The wear and corrosion properties are improved significantly by PIII-IBED techniques.
