Zinc cobalt alloy plating |
摘要 |
The present invention relates to an improved electroplating bath and process for producing semi-bright to bright zinc cobalt alloy electrodeposits on substrates, and particularly non-planar substrates, to provide enhanced resistance to salt spray corrosion. The invention further contemplates the application of a thin passivate coating directly on the zinc-cobalt electrodeposit, or alternatively, on a substantially pure zinc flash over plate of a thickness sufficient to enable the zinc flash to be converted to an adherent substantially continuous zinc passivate.
