【Abstract】 High voltage anodic aluminum foils were prepared by a combined methods of constant current and constant voltage.The effects of NH4B5O8 added to the H3BO3 solution on the surface tension,conductivity of the formation solution and the withstand voltage and specific capacitance of the formed anodic foils were investigated.The mechanism of the NH4B5O8 in the formation solution was analyzed.The results show that the microamount of NH4B5O8 added to the H3BO3 formation solution can increase the surface tension and conductivity of the formation solution,change the ionization of the formation solution and improve the withstand voltage of the formed anodic foils by about 5%.更多还原
