摘　　要：提出了一种电镀枪色镍锡合金的新方法：以硫酸镍、硫酸亚锡为主盐，葡萄糖酸钠为络合剂，分别加入钼酸铵、氨基酸以及本文研究的含硫氨基化合物等添加剂，可以方便地获得褐色、铁灰、黑友以及茶黑色等4种不同色调的枪色镀层。主盐和络合剂的浓度、阴极电流密度的变化都会对镀层的镍含量产生影响，镍含量提高将使镀层的色调加深。镀液无毒、无腐蚀性、稳定性好。A newly developed gun color Ni-Sn alloy electroplating process is introduced in this paper. Nickel sulfate and stannous sulfate are metallic salts and sodium glu-conate is used as complexing agent. Brown, iron grey,dark grey and dark brow-black Ni-Sn alloy can be con-veniently obtained when ammonium molybdate, amino acids and amino compound containning sulfur investi-gated in this paper are added in baths respectively.Concentration of metallic salts and complexing agent,and cathodic current density can affect the nickel con-tent in the deposit. The bath solution is non-toxic,non-corrodent and of long-term stability.
