Soluble zinc and insoluble low carbon steel anodes are used for alkaline zinc-cobaltplating.
碱性锌钴合金电镀常采用锌阳极和低碳钢阳极。
2
Zinc and cobalt content in zinc cobalt alloy plating bath should be maintained in a suitable range so that corrosion resistant zinc cobalt alloy deposit can be obtained.
为获得耐蚀性良好的锌钴合金镀层，必须维持镀液中的锌钴含量在工艺范围内。
3
Zinc and cobalt content in zinc cobalt alloy plating bath are determined by the combined method of titration with EDTA and spectrophotometry.
