    • 工業泛用之鋼板的防蝕技術常利用金屬包覆方法，由於鋅鍍層相較於其他金屬對Cl-有良好的抵抗效果並較經濟，所以多運用在海洋氣氛中的鋼鐵材料上。常用的鍍鋅方法有熱浸鍍鋅法、電鍍法和利用真空爐或流體床的CVD/PVD法，但考量到成本、環境、工件尺寸與連續化製程上的缺點，若使用固態粉體擴散法來製成鋅鍍層，則可透過溫度控制等製程參數，得到相當一致的膜厚。本研究利用固態粉體擴散法得到在鍍鋅製程中的最佳參數為加熱溫度400℃下持溫2小時，且添加2% NH4Cl對於鍍層的完整性有明顯的提高，並且發現在一定次數的製程循環內，所使用的鋅粉有回收再利用性。經由擴散所形成的鍍層結構與熱浸鍍鋅的鍍層有相同的成長機制，鍍層厚度會與製程時間的平方根呈線性關係，添加鋁粉雖然會使鍍層厚度減少，卻能在鹼性環境中提供良好的耐腐蝕能力。電化學測試結果也顯示，鋅鍍層在鹼性環境中可以提供最佳的犧牲保護效果，除此之外，由固態粉體擴散滲鋅法製成的鍍層在鹼性環境中擁有最高的腐蝕電位，能降低腐蝕的發生機率並提供更好的耐蝕性。

    Zn coating is better and cheaper than other metal coatings in resisting the Cl- ion corrosion, so it is widely used for protecting the steel tools which are working under seawater environment. Lately the coating methods like hot-dip galvanizing, electroplating and CVD/PVD by using vacuum furnace or fluidized bed are extensively applied in fabricating of Zn coating. But, it still exists some problems with cost, environment pollution, and workpiece measurement in continuous process by using these coating methods. Solid-diffusion coating method can form a continuous Fe-Zn outer layer in uniform thickness by controlling the process conditions. In this study, Zn coating is formed using solid-diffusion coating method by heating the substrate to 400℃ for 2 hours. The multi-layer films not only enhance the corrosion resistance and surface hardness, but also improve the recyclability and reusability of Zn powder by some specific repeated cycles. Although the addition of Al powder in Zn coating reduces the coating thickness, it improves the anti-corrosion property under alkaline environment. After electrochemical analysis, the Zn coatings made by solid-diffusion method reveal the best corrosion resistance and the highest corrosion potential under alkaline environment. So we can expect the Zn coating with lower corrosion probability to provide better sacrificed protection.
