Impact of Surface Preparation and Tank Maintenanceon Nickel Corrosion Resistance

摘要

Electrodeposited nickel is used for many purposes including corrosion resistance. Porosity in therndeposit will decrease that protection. Good control of surface preparation parameters, includingrnabrasive blasting, electrocleaning and sulfuric-hydrofluoric acid etching was proven to be veryrnimportant. Nickel-plating tank maintenance such as solution filtration and agitation, anodes andrnanode bags and removal of excess precipitates were also investigated. Improvement of the nickelrncorrosion resistance was obtained under specific conditions, and will be reported here.
