摘 要: 在熱鍍鋅熔液中添加Mn， Ti及Ni， Ce, Cu等元素，通過控制鍍液溫度及冷卻條件， 直接在鋼板上獲得了綠色、 紫色、 藍色、 黃色等色彩， 這種多元添加獲得的彩色鍍鋅熔液性能優(yōu)良； 采用百分制方法成功地對彩色鍍鋅試樣的優(yōu)劣作出了較好的評價，并通過正交試驗優(yōu)化了合金的含量， 得到兩種最優(yōu)熔液， 即Zn-0.1Mn-0.05Ni-0.01Cu和Zn-0.15Ti-0.1Mn-0.1Ce-0.05Ni-0.01Cu。實驗驗證了正交結果的可靠性。

Abstract:Through controlling the immersing temperature of baths and its contents of Mn, Ti, Ni, Ce and Cu， the green, purple, blue and yellow colors were achieved directly on the steel sheets. This kind of coloring zinc baths, obtained by multipleadditives, has good properties. Percentage method was used successfully to estimate the coloration of samples, and the composition of bath was optimized by orthogonal analysis; and the optimum baths are gained as Zn-0.1Mn-0.05Ni-0.01Cu and Zn-0.15Ti-0.1Mn-0.1Ce-0.05Ni-0.01Cuwhich were verified by experiments.
