| 中文摘要: |
| 采用双层辉光等离子渗金属技术,在工业纯铁表面渗入Cr,Mo,Co等合金元素,可在其表面形成与沉淀硬化不锈钢合金含量及硬度水平相近的合金层。以SEM 等对比研究了不同工艺参数下,等离子渗入合金元素后,合金层表面的微观形貌。通过对比不同温度、源极电压所对应的渗层成分及厚度,选择出最优化的工艺参数:源极电压1350V,阴极电压510~530V ,加热温度1100V,保温时间5h。 |
| 英文摘要: |
| Using the double glow plasma surface alloying technique, with the industrial pure iron surface into Cr,Mo,Co and other alloy elements, can be formed on the surface and precipitation hardening stainless steel alloy content and hardness level similar to that of the alloy layer. With SEM studied plasma into the alloy elements alloy layer of surface micro morphology under different process parameters. According to the different temperature, the voltage of the source electrode corresponding to the layer composition and thickness between studies, choose the optimized processparameters: the source voltage is 1 350 V, cathode voltage is 510~530 V, the heating temperature is 1100 ℃, heat preservation time is 5 h. |
