Die Annotation des Normtextes ASTM B343-92a(2020) :

This practice summarizes well-known, generally practical methods for producing adherent electrodeposits of nickel on nickel. The types of nickel for which an overplate of nickel may be desired are dull nickel, semi-bright nickel, bright nickel, and nickel strike. The following cleaning treatments may be used for all conditions and types of electrodeposited nickel: degreasing and electrolytic alkaline cleaning. The procedures should be used for etching or activating the nickel surface are the following: anodic treatment in concentrated sulfuric acid; anodic etching in sulfuric acid; anodic etching in watts-type bath; acid-nickel chloride treatment; etching by acid immersion; electropolishing treatment; and cathodic treatment.
