Through adding assistant complexing agent and controlling initial current density, cathodic polarization was intensified in cyanide-free electrolyte.

通过添加辅助络合剂和控制起始电流密度的方法，可以增强无氰电镀时阴极的极化。

Results show that it is difficult to make cathodic protection on bare steel because of large current density, and that cathodic protection is suitable for coated steel.

试验结果表明，对裸钢采用阴极保护时，所需电流密度较大，实施难度较大；而对有涂层的钢则更宜采用阴极保护措施。
