工艺条件的控制直接影响着电镀层的质量。只有掌握和控制好每个镀种的各工艺条件,才能获得优质镀层。温度、电流密度、pH值、电镀时间等工艺条件必须相匹配。如在镀硬铬时,温度和电流密度配合不当,对镀铬溶液的阴极电流效率、分散能力、镀层硬度和光亮度都有很大的影响。如下图,当温度较高时,需适当增加电流密度,才可以获得所需的镀层。二者互相制约,改变其一,另一因素必须跟着变化。因此对工艺条件控制不好,就会发生电镀质量事故。

零件的电镀质量作为产品零件整体质量的一个环节,不仅受电镀工艺及电镀车间内部环节的影响,而且还不同程度地受企业其他生产环节和生产、技术部门的影响,这些因素往往非常容易被忽视,我们应该对这些因素有一个全面的认识。

在大气条件下,黑色金属用锌镀层来防止腐蚀。但当锌镀层接触到酚醛漆类、醇酸漆、酚醛塑料、潮湿的木材、胶合板等,对锌镀层的腐蚀是相当严重的,时间越长腐蚀产物越厚,这是少量有机挥发气氛对大气腐蚀的加速作用,叫做气氛腐蚀。能产生这样的有机挥发气氛的物质有:油漆、塑料、树脂、木材等。气氛腐蚀的腐蚀速度与有机挥发气氛的浓度有很大关系,浓度越高,腐蚀越严重。但是,有机挥发气氛只有在潮湿的大气中,才能腐蚀锌镀层,如果只有腐蚀气氛,而周围空气很干燥,则基本上不出现腐蚀现象,因此在大气中,只有在没有有机挥发气氛或者完全干燥空气的条件下,锌镀层才是可靠的防护性镀层。电镀合格的零件在储存过程中,一定保证库房的环境,避免零件发生气氛腐蚀。另外,在运输过程中,产品包装直接影响零件抗腐蚀能力。因此必须最大限度地减少有机挥发气氛源,镀锌件一定要用木箱包装存放,要加可靠的内包装,并放入干燥剂,以保证零件与外界腐蚀氛围完全隔离,否则零件极容易锈蚀,影响产品质量,造成不良影响。这些外部因素非常容易被我们忽视,成为影响电镀质量的重要因素。
