Beschreibung
Zusammenfassung:	Provided are a tin/magnesium thin film formed on a zinc-plated layer and a manufacturing method thereof. The manufacturing method of a tin/magnesium thin film comprises the steps of: preparing a substrate having a zinc-plated layer; depositing magnesium (Mg) and tin (Sn) on the surface of the zinc-plated layer to form a magnesium thin film and a tin thin film; and diffusing zinc, magnesium and tin atoms through thermal treatment to form a thin film having an intermetallic compound in which tin and magnesium are contained. The present invention provides shielding effects and sacrificial anode properties by diffusion movement between components and formation of an intermetallic compound through physical deposition and heat treatment, and can manufacture the tin/magnesium thin film on the zinc-plated layer rapidly, stably and precisely by controlling an influence of crystal orientation according to manufacturing conditions. 본 발명은, 아연도금층에 형성되는 주석/마그네슘 박막 및 그 제조방법에 있어서, 아연도금층이 형성된 기판을 준비하는 단계와; 상기 아연도금층의 표면에 마그네슘(Mg) 및 주석(Sn)을 물리증착하여 마그네슘박막 및 주석박막을 형성하는 단계와; 열처리를 통해 아연, 마그네슘 및 주석원자가 확산이동하여 주석/마그네슘 상호고용 및 금속간 화합물이 존재하는 박막을 형성하는 단계를 포함하는 것을 기술적 요지로 한다. 이에 의해 물리증착법 및 열처리를 통해 성분간 확산이동, 금속간 화합물 형성으로 인해 차폐 효과 및 희생양극 특성을 부여함은 물론, 제작조건에 따른 결정배향성의 영향을 종합적으로 고려 제어함으로써 안정적이고 치밀-안정적으로 빠르게 생성가능하도록 주석/마그네슘 박막이 아연도금 기판 상에 제조되는 효과를 얻을 수 있다.
