A vacuum coating method for the surface of an aluminum alloy wheel comprises the following steps of: grinding and polishing the surface of an aluminum wheel; cleaning; performing chemical passivation treatment on the surface of the aluminum wheel; performing plasma treatment on the surface of the aluminum wheel; performing PVD blue coating; and spraying transparent powder. By the method, the polished surface of the aluminum alloy wheel is coated with a blue glossy film in a vacuum, and the powder transparent coating layer is sprayed, so the outer appearance of the wheel is blue, glossy, beautiful and elegant, and corrosion resistance of the coating layer is excellent, thereby satisfying the increasing demand for personalization of people.

    본 발명의 알루미늄 합금 휠 표면의 진공 코팅 방법은, 알루미늄 합금 휠의 표면을 그라인딩 및 폴리싱하는 단계; 세정 단계; 알루미늄 합금 휠의 표면을 화학적 패시베이션 처리하는 단계; 알루미늄 합금 휠의 표면을 플라즈마 처리하는 단계; PVD 청색 코팅하는 단계; 및 투명 분말을 스프레이하는 단계를 포함한다. 상기 방법을 통해 알루미늄 합금 휠의 폴리싱 표면에 청색 광택 필름을 진공 코팅하고 분말 투명 코팅층을 스프레이함으로써, 휠의 외관이 청색 광택나고 미관적이면서 대범하며 코팅층의 내식성이 우수하여 날로 증가하는 사람들의 개성화 요구를 만족할 수 있다.
