Title (EN) SURFACE TREATMENT METHOD FOR METAL BASE
(FR) PROCÉDÉ DE TRAITEMENT DE SURFACE D'UNE BASE MÉTALLIQUE
(KO) 금속기재의 표면처리방법
Abstract: front page image
(EN)The present invention is applied to exterior and interior materials, external cases, housings, and bodies, etc., made of metal, in cellular phones, laptop computers, various electronic devices, vehicles, aircrafts, and ships, etc., and is capable of improving durability, corrosion resistance and coating adhesion, etc. while increasing metallic texture through surface treatment of forming a passivation layer, a heterogeneous metallic protective layer, and a coating protective layer, etc. on the surface and structure pattern of an easily oxidized metal base such as magnesium, magnesium alloy, aluminum, aluminum alloy, titanium, titanium alloy, copper, copper alloy, silver, silver alloy, etc. The present invention relates to a surface treatment method for a metal base made of any one among magnesium, magnesium alloy, aluminum, and aluminum alloy, the surface treatment method comprising the steps of: heating an alcohol-based or ketone-based passivation solution at a heat temperature for passivation treatment; and forming a passivation layer on the surface of the metal base through a reaction with the passivation solution in the state that the metal base is dipped into the alcohol-based or ketone-based passivation solution heated at the heat temperature for passivation treatment.
(FR)La présente invention est appliquée à des matériaux d'extérieur et d'intérieur, des étuis externes, des boîtiers, et des corps, etc., constitués de métal, dans des téléphones cellulaires, des ordinateurs portables, divers dispositifs électroniques, des véhicules, des avions et des bateaux, etc., et permet d'améliorer la durabilité, la résistance à la corrosion et l'adhérence du revêtement, etc. tout en augmentant la texture métallique par le biais d'un traitement de surface consistant à former une couche de passivation, une couche de protection métallique hétérogène, et une couche de protection de revêtement, etc. sur la surface et un motif de structure d'une base métallique facilement oxydée telles que du magnésium, un alliage de magnésium, de l'aluminium, un alliage d'aluminium, du titane, un alliage de titane, du cuivre, un alliage de cuivre, de l'argent, un alliage d'argent, etc. La présente invention concerne un procédé de traitement de surface d'une base métallique constituée de l'un quelconque parmi le magnésium, un alliage de magnésium, l'aluminium, et un alliage d'aluminium, le procédé de traitement de surface comprenant les étapes consistant à : chauffer une solution de passivation, à base d'alcool ou à base de cétone, à une température de chauffage permettant le traitement de passivation; et former une couche de passivation sur la surface de la base métallique par le biais d'une réaction avec la solution de passivation dans l'état où la base métallique est immergée dans la solution de passivation, à base d'alcool ou à base de cétone, chauffée à la température de chauffage permettant le traitement de passivation.
(KO)본 발명은 휴대폰이나 노트북 및 각종 전자기기, 자동차, 항공기, 선박 등의 금속으로 구비된 내외장재, 외장 케이스(Case)나 하우징(Housing), 바디(Body) 등에 적용되는 것으로, 마그네슘, 마그네슘 합금, 알루미늄, 알루미늄 합금, 티타늄, 티타늄 합금, 동, 동 합금, 은, 은 합금 등과 같은 산화가 용이한 금속기재의 표면과 구조물 패턴(Pattern)에 대해 부동태층(不動態層)을 비롯한 이종(異種)금속 보호층, 도막(塗膜) 보호층 등을 형성시킨 표면처리를 통해서 금속 질감을 높여줌과 함께 내구성, 내식성, 도막 밀착성 등을 향상시켜 줄 수 있도록 한 것이다. 이와 같은 본 발명은 마그네슘, 마그네슘 합금, 알루미늄, 알루미늄 합금 중에서 어느 하나로 구비된 금속기재의 표면처리방법에 있어서, 알코올(Alcohol)계 또는 케톤(Ketone)계의 부동태 용액을 부동태처리 열온도로 가열시켜 주는 단계; 상기 부동태처리 열온도로 가열된 알코올계 또는 케톤계의 부동태 용액에 금속기재를 침적시킨 상태에서 상기 부동태 용액과의 반응에 의해 상기 금속기재의 표면에 부동태층(不動態層)을 형성시켜 주는 단계 포함한 것을 그 특징으로 한다.
