| Description |
Electrochemical techniques can rapidly evalute the quality of electroplated finishes relatively faster than the conventional long-term neutral salt spray test. In addition to quantifying the corrosion, they also yield mechanistic information about the corrosion process. One such application of these techniques to evaluate the corrosion resistance of zinc coatings is discussed. Comparison of two zinc coatings shows that deposits from a non-cyanide zinc bath provide excellent corrosion resistance in contrast to those from a cyanide zinc bath. Of the three types of chromate coatings tested, the least protection is provided by the blue chromate; the most protection is from olive green chromate passivation
