结果表明,由于Pb元素的共价半径大和表面能低,导致Pb具有很强的偏析能力,而Cu的偏析能力相对较弱。 |
The results showed that Pb element had strong segregation ability owing to its large covalent radius and low surface energy, while the segregation of Cu is relatively weak. |

Pb和Cu主要富集在铝箔表面50~60 nm附近,富集位置取决于杂质原子半径,而与偏析能无关。 |
Pb and Cu were mainly concentrated at the depth of 50-60 nm near the aluminum foil surface, and the concentrated position was dependent on the atomic radius instead of the segregatior energy of the impurity atoms. |

另外,由于邻位Pb原子更容易使表面结构驰豫,铝箔内部Pb倾向于维持粒子形态,而Cu没有表现出很明显的聚集倾向,在原子形态和粒子形态之间保持一种平衡。 |
In addition, Pb tended to maintain the particle form in the aluminum foil due to the preferential relaxation of surface structure for ortho Pb atoms. In contrast, Cu did not show significant aggregation, instead, a balance between the atomic form and the particle form of Cu was kept. |

因此高压光箔中Pb和Cu表现出不同的固溶状态。 |
Therefore, Pb and Cu exhibited different solid solution states in high-voltage aluminum foil. |

结果表明:与传统端涂工艺相比,蘸浆端涂工艺不仅彻底地摆脱了对于高精度封端设备和工装夹具的依赖,生产成本较低,而且更适用于小尺寸产品端电极的制备; |
The results show that compared with the traditional end coating process, the dipping paste end coating process not only gets rid of the dependence on the high-precision end coating equipment and fixture, but also has a lower production cost, which is more suitable for the preparation of terminal electrode of small-size product. |

同时,薄膜溅射工艺制备的端电极层具有更高的致密性,这不仅解决了端涂工艺制备端电极推球实验不合格问题,显著提高了引出端电极的焊接可靠性。 |
Meanwhile, the terminal electrodes prepared by thin film sputtering process has a higher density. This process improves the qualification of the terminal electrode wire bond shear test, and the terminal electrode welding reliability can be improved. |
