Abstract
본 발명에 따른 도금 강판의 제조방법은 강판 위에 알루미늄층을 코팅하는 단계; 알루미늄층에 마그네슘층을 코팅하는 단계; 및 알루미늄층 및 마그네슘층이 코팅된 강판을 열처리하여 알루미늄-마그네슘 혼합층을 형성시키는 단계;를 포함한다.
본 발명의 실시예들에 따르면 알루미늄과 마그네슘으로 이루어지는 균일한 합금 코팅층을 형성함으로써, 강판과 코팅층 간의 밀착력을 향상시킬 수 있다. 또한 본 발명의 실시예들에 따르면 알루미늄과 마그네슘으로 이루어지는 균일한 합금 코팅층을 형성함으로써, 내식성 및 기계적 특성을 향상시킬 수 있다.
Description
도 2는 본 발명의 일 실시예에 따른 도금강판의 X선 회절 그래프이다.
