摘　　要：采用由500 g/L Ni(NH2SO3)2·4H2O、30 g/L H3BO3和30 g/L NiCl2·6H2O组成的镀液对高碳钢丝预镀镍,以制作晶体硅太阳能电池片切割用电镀金刚石线锯.研究了镀液pH、温度和电流密度对预镀镍层表面形貌、结合力和抗拉强度的影响.得到较优的预镀工艺条件为:pH 4.5,温度55℃,电流密度3.5 A/dm^2.该条件下所得预镀镍层细致、平整,与母线结合良好,抗拉强度达3403.5 MPa.High-carbon steel wire was pre-plated with nickel in a bath comprising Ni(NH2SO3)2·4H2O 500 g/L,H3BO330 g/L,and NiCl2·6H2O 30 g/L to prepare diamond wire saw by electroplating for cutting crystalline silicon solar cell plates.The effects of current density,temperature,and pH on the surface morphology,adhesion,and tensile strength of pre-plated nickel coating were studied.The optimal process conditions were obtained as follows:temperature 55℃,pH 4.5,and current density 3.5 A/dm^2.The nickel coating pre-plated under the given conditions features compactness,smoothness,good adhesion to wire substrate,and a tensile strength up to 3403.5 MPa.
