  • Patent number: 6827834
    Abstract: The invention consists of a method for producing an adherent copper coating on a zinc or zinc alloy article without the use of cyanide as a component of the process. The zinc or zinc alloy article is first immersed in an aqueous nickel pyrophosphate solution and is then electroplated with a copper pyrophosphate solution. The method produces an adherent copper coating on the zinc or zinc alloy, which can be deformed without any loss of the copper coating.

  • Patent number: 4444630
    Abstract: Acid electroplating baths for bright zinc plating containing a zinc salt, ammonium chloride and bath additives which include a carrier component comprising an alkyl substituted ammonium propoxylate salt, preferably a trialkylammonium propoxylate salt, and a lower molecular weight alkyl substituted naphthalene sulfonic acid, or bath soluble salt thereof, in combination with other brighteners and grain refiners for providing bright, ductile, fine grained, adherent deposits over a broad current density range.

  • Patent number: 4081336
    Abstract: An alkaline, electroplating bath for bright zinc plating comprising a heterocyclic nitrogen-containing compound such as, for example, nicotinic acid, which has been alkylated with a condensate of a difunctional halohydrin such as, for example, epichlorohydrin, and a hydroxy aryl compound such as, for example, vanillin, in admixture with certain polyethylenepolyamines or quaternary salts thereof, which bath is capable of producing bright, fine grained zinc deposits over a broad current density range both in the presence and absence of cyanides.
