电镀的材料要求
      镀层大多是单一金属或合金,如钛靶、锌、镉、金或黄铜、青铜等;也有弥散层,如镍-碳化硅、镍-氟化石墨等;还有覆合层,如钢上的铜-镍-铬层、钢上的银-铟层等。电镀的基体材料除铁基的铸铁、钢和不锈钢外,还有非铁金属,或ABS塑料、聚丙烯、聚砜和酚醛塑料,但塑料电镀前,必须经过特殊的活化和敏化处理。
电镀的原理
      在盛有电镀液的镀槽中,经过清理和特殊预处理的待镀件作为阴极,用镀覆金属制成阳极,两极分别与直流电源的负极和正极联接。电镀液由含有镀覆金属的化合物、导电的盐类、缓冲剂、pH调节剂和添加剂等的水溶液组成。通电后,电镀液中的金属离子,在电位差的作用下移动到阴极上形成镀层。阳极的金属形成金属离子进入电镀液,以保持被镀覆的金属离子的浓度。在有些情况下,如镀铬,是采用铅、铅锑合金制成的不溶性阳极,它只起传递电子、导通电流的作用。电解液中的铬离子浓度,需依靠定期地向镀液中加入铬化合物来维持。电镀时,阳极材料的质量、电镀液的成分、温度、电流密度、通电时间、搅拌强度、析出的杂质、电源波形等都会影响镀层的质量,需要适时进行控制。
电镀的要素
      电镀的要素: 1.阴极:被镀物,指各种接插件端子。 2.阳极:若是可溶性阳极,则为欲镀金属。若是不可溶性阳极,大部分为贵金属(白金,氧化铱)。 3.电镀药水:含有欲镀金属离子的电镀药水。 4.电镀槽:可承受,储存电镀药水的槽体,一般考虑强度,耐蚀,耐温等因素。 5.整流器:提供直流电源的设备。
电镀生产的基本工序
(磨光→抛光)→上挂→脱脂除油→水洗→(电解抛光或化学抛光)→酸洗活化→(预镀)→电镀→水洗→(后处理)→水洗→乾燥→下挂→检验包装
