这里介绍一种不用外加直流电源腐蚀铝的工艺方法,能大量消除腐蚀过程中被腐蚀的铝表面产生的氢气泡,也就消除了铝斑。这种方法的主要之点是将铝腐蚀过程中的电荷转移用外加电极的方法加以导引,使气泡由铝表面释放转移到外加电极上释放,效果显著,也为判断感光胶对铝的粘合力的优劣提供了一个适当的方法 Here is a non-DC power supply technology to corrode aluminum can be a large number of corrosion process to eliminate corrosion of aluminum surface hydrogen bubbles, which eliminates the aluminum spot. The main point of this method is that the charge transfer in the process of aluminum corrosion is guided by an external electrode so that the bubbles are released from the surface of the aluminum to be transferred onto the external electrode for release and the effect is remarkable. The merits of the force provides an appropriate method
