금속염함유의 전해액과 교류전기를 사용하여 알루미늄 또는 그 합금에 형성된 양극산화피막을 2차적으로 전해처리하여 착색시키는 방법을 수행함에 있어서, 전술의 양극산회피막을 전술의 전해액속에서 금속성분의 석출이 없는 정도로 낮은 전압의 교류전기로 적어도 20초 이상으로 되는 시간동안의 예비적전해처리를 우선적으로 수행하며, 다음의 단계에서 교류전압을 금속성분이 석출되는 전압에까지 상승시키고서 2차전해처리를 수행함에 있어서는, 전압의 상승을 2단계 이상의 여러단계로 나누어서 수행하며, 또 이 2차적전해처리시에 그 양극산화피막을 음극으로 되게 하는 방향의 전류분량이 같은 교류전압으로 처리중에 경시적증가가 없도록 조절하고서 2차적전해처리를 수행함을 특징으로 하는 알루미늄 또는 그 합금의 양극산화피막에 대한 전해착색방법.In the method of secondary electrolytic treatment of the anodized film formed on aluminum or its alloy using a metal salt-containing electrolyte and alternating current electricity, the deposition of the metal component in the aforementioned electrolyte solution is carried out. Preliminary electrolytic treatment for a period of at least 20 seconds is preferentially performed with an alternating current of low voltage, and in the next step, the secondary electrolytic treatment is performed by raising the alternating voltage to the voltage at which the metal component is deposited. The voltage rise is divided into two or more steps, and the current amount in the direction of making the anodized film become the cathode during the second electrolytic treatment is controlled so that there is no increase over time during the treatment with the same AC voltage. For anodizing film of aluminum or its alloys, characterized by performing secondary electrolytic treatment Electrolytic Coloring Method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
