摘要
由于其优良的抗腐蚀性,电镀后的钢材在许多行业中得到了广泛的使用。硅是一种常用的除氧化剂,也是一种增强材料强度的成分,由于在热镀锌过程中,含有硅的活性钢会产生硅能使镀层变厚,从而影响到热浸镀锌工业的发展。本文研究了碳、硅、磷、铜、钛等元素对热镀锌的显微结构和力学特性的影响。研究发现,在锌液中加入Al、Mg、Ni及少量Ri后,可使Zn的显微结构变细,结构变得更为致密、均一,使镀层的厚度有所减小,使其耐腐蚀性能有所提高。
Because of its excellent corrosion resistance, galvanized steel has been widely used in many industries. Si is a commonly used oxidant and a component to enhance the strength of materials. In the process of hot-dip galvanizing, the active steel containing silicon will produce silicon which can make the coating thicker, thus affecting the development of hot-dip galvanizing industry. The effects of carbon, silicon, phosphorus, copper, titanium and other elements on the microstructure and mechanical properties of hot dip galvanizing were studied. It is found that adding Al, Mg,Ni and a small amount of Ri into the zinc bath can make the microstructure of Zn finer, the structure more compact and uniform, reduce the thickness of the coating, and improve its corrosion resistance.
