碱性电镀锌钴合金阳极行为的研究

Study of anodic behavior in alkaline zinc-cobalt bath

碱性锌钴合金电镀常采用锌阳极和低碳钢阳极。研究了锌和低碳钢阳极在碱性锌镍合金镀液中的溶解特性及阳极极化行为。结果表明 ,采用锌和低碳钢混挂阳极 ,控制其面积比 。

Soluble zinc and insoluble low carbon steel anodes are used for alkaline zinc-cobalt plating. Dissolution of zinc and low carbon steel anodes and anodic polarization behaviors thereof were studied. Results show that concentration of zinc ions keeps constant when zinc and low carbon steel anodes are used in combination with proper area ratio.
