• 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.    .

• Defects in Hard Chromium Deposits Part I: Causes and Cures

  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.
