Embodiment
Set forth in detail in the face of preferred embodiment of the present invention down, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Embodiment one
Test starting material 1) sample base material Q235, thickness 0.35mm is through Passivation Treatment before zinc-plated.Sample requires: A4 paper size, mark pros and cons.2) purity of required raw material zinc is 99.997%, and element purity such as all the other metal M n, Ti, Ni, Cu and Ce all reach 99. 99%.6% metal detergent is water-soluble, 10% (volume(tric)fraction) hydrochloric acid, 35% ZnCl
23NH
4The Cl aqueous solution.3) required equipment electronic balance, zinc pot, volumetric flask, beaker, wide-necked bottle, drop bottle etc.Experimentation 1) solution preparation preparation Zn 25. 1%Mn, Zn 23. 3% Ti, Zn 22. 9%Ni and Zn 22. 58%Ce (except that particularly pointing out, being massfraction) master alloy.
The color configuration plating bath that appears as required mainly demonstrates yellow such as needs, then can increase the activity of content or the increase Cu of Cu, and the mixing that need present multiple color then can evenly add the content of Cu, Mn and Ti, and makes their active basically identical.
In 400-650 ℃ of scope, add Ni in Zn-Mn and Zn-Ti two plating baths activity of solvent Zn is improved, Cu is very little to the influence of solution activity in this temperature, and Ti has significantly improved the activity of Zn in the solvent.
