Abstract

본 발명은 엠보싱된 알루미늄 및 알루미늄 합금의 표면처리 방법에 관한 것이다.The present invention relates to a method of surface treatment of embossed aluminum and aluminum alloy.

모재표면의 평활성 및 수려한 광택을 갖게하고 또한 엠보싱 무늬가 선명히 표출되게 하며 내식성과 내마모성, 내후성을 향상시키는데 목적이 있다.It aims to have smoothness and beautiful luster of the surface of the base material and to make the embossed pattern appear clearly and to improve corrosion resistance, abrasion resistance and weather resistance.

전해액중에서 금속이 양극 용해하는 것을 이용하여 모재를 양극으로 하여 전해함으로서 모재표면의 요철부를 우선적으로 용해시켜 모재표면의 평활성과 광택을 부여하며 모재표면에 산화물의 피막을 형성시켜 알루미늄 및 알루미늄합금의 표면은 평활함은 물론 수려한 광택과 엠보싱 무늬가 선명히 표출되며 내식성 및 내마모성, 내후성을 향상시키고자 하는 것이다.By dissolving metal in the electrolyte in the electrolyte, the base metal is used as the anode to dissolve the uneven parts of the base material, giving smoothness and luster to the base material surface, and forming an oxide film on the surface of the base material. Not only smoothness but also beautiful luster and embossed pattern are clearly expressed, and it is intended to improve corrosion resistance, abrasion resistance and weather resistance.
