Evaluation of Atmospheric Corrosion on Electroplated Zinc and Zinc-Nickel Coatings by Electrical Resistance (ER) Monitoring
This paper is a peer-reviewed and edited version of a presentation delivered at NASF Sur/Fin 2013 in Rosemont, Ill., on June 12, 2013.
The causes of and remedies for defects in hard chromium deposits are explored in the first of this two-part P&SF article from 1984. Photomicrographs and SEM (scanning electron microscope) photographs will illustrate that most defects in various hard chromium deposits arise from defects in the basis metal. These defects may be in the original metal surface or may be caused by preplate finishing. Homogeneous hard chromium deposits can be produced only by eliminating these defects. Practical suggestions and procedures will be given.
Research at the authors’ laboratories has focused on pulse/pulse reverse electrolysis on cathodic processes, such as hard chromium plating from non-hexavalent chemistries. This papers describes studies into pulse/pulse reverse electrolysis as applied to electrochemical metal removal processes, such as electropolishing and electroetching.
