用重熔结晶二次电镀的方法获得了不同类型的晶纹．通过赫尔槽试验确定了最佳电流密度范围．在此基础上，对重熔、冷却、浸蚀、二次镀等工艺过程的参数进行了筛选．结果表明，控制晶纹花型的主要因素是重熔和冷却的协同作用．水冷易得较美观的花纹，适当的重熔温度和重熔时间可使晶纹更细致柔和．其原因是上述两步骤决定了晶粒的形核与长大． Different types of grains were obtained by remelting secondary plating. The best current density range was determined by Hull cell test. On this basis, the parameters of remelting, cooling, etching, secondary plating and other technological processes were screened. The results show that the main factor controlling the grain pattern is the synergistic effect of remelting and cooling. Easy to get more beautiful water-cooled pattern, the appropriate remelting temperature and remelting time can make the grain more delicate and soft. The reason is that the above two steps determine the grain nucleation and growth.
