中文摘要: |
采用逐层沉积的方法,在基材表面获得了1-8层Ni基电火花涂层,探讨了电火花沉积过程中Ni基电极的质量过渡规律及电极材料的流失形式。结果表明:Ni基电极向基材的平均质量过渡系数为0.76;电极的损失有气化、液态溅射和氧化三种形式;氩气保护在沉积过程中起重要作用;随着沉积层厚度的增加,基材对涂层的稀释越来越小。 |
英文摘要: |
The one to eight Ni-based coatings were prepared by electrospark deposition (ESD)technique using layer by layer method.Mass transfer regularity and loss form of Ni-based electrode were explored. The results show that the average mass transfer coefficient from electrode to substrate is about 0.76; The mass loss of the electrode presents as gasification, splash of molten drops and oxidation; The shielding gas, for example the gas Ar, plays an important role during ESD process; The dilution of the substrate to the coating is becoming lower and lower with the increasing thickness of the ESDcoating. |
