摘要
固定其它工艺参数,改变镀液pH值和柠檬酸钠含量对ZAT10变形锌合金进行电镀镍,通过金相显微镜、场发射扫描电镜(SEM-EDS)和超景深三维显微镜记录镀镍层的形貌,以镀液稳定性、镀层表观合格性和出现裂纹与否为依据,对整个实验区进行划分,获得了关于镀液pH值-镀液柠檬酸钠含量与镀液稳定性和镀层性能的关系示意图,并结合EDS分析镀层成分和涂膏法、热震试验分析镀层性能的结果,最终确定了示意图上镀液稳定、镀层质量好的区域。
After regulating the other technological parameter,changing the pH value and sodium citrate content,the ZAT10 deformed zinc alloy was electroplated with Ni.The morphology of nickel coating was recorded with optical microscopy,scanning electron microscopy（SEM-EDS） and ultra-depth three-dimensional microscopy.Based on the stability of electroplating solution and surface property,the test region was classified.And the schematic diagram of pH-sodium citrate content of electroplating solution vs stability of electroplating solution and coating property was obtained.The optimal region with stability plating solution and good coating on the diagram was defined by the results of plating composition analysis obtained by EDS and coating property analysis obtained by paste method and thermal shock test.
