• A Pulse/Pulse Reverse Electrolytic Approach to Electropolishing and Through-Mask Electroetching

  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.

• Cyanide Destruction: A New Look at an Age-Old Problem

  Cyanide in mining and industrial wastewaters has been around from the beginning, including electroplating processes.  This presentation reviews a number of current processes, and in particular, offers new technologies for improvement in cyanide destruction by the most common process, using sodium hypochlorite.

• A Process for Alkaline Non-cyanide Silver Plating for Direct Plating on Copper, Copper Alloys and Nickel Without a Silver Strike Bath

  Traditionally, silver is electroplated in toxic, cyanide-based chemistry.  Due to cyanide’s extreme hazard to human health and environments, developing non-cyanide silver chemistry is essential for the silver electroplating industry.  Discussed here is an aqueous, alkaline non-cyanide silver plating technology, which can be directly plated over nickel as well as copper and its alloys.  The silver deposits have perfect white color and better anti-tarnishing properties than other non-cyanide silver processes.  The silver is plated entirely from the dissolving silver anode and the bath is very stable, and maintains a stable pH level both during plating and idle time.  This new non-cyanide silver technology will plate bright silver that is perfectly suitable for electronic, industrial and decorative applications.    .
