Guys Like Ray Lucas Make A Shining Example
Having the U.S. Environmental Protection Agency show up at your front door on a Monday morning is never a good sign—kind of like Mike Wallace and a 60 Minutes crew, or maybe even your in-laws. But Ray Lucas and his employees at Valley Chrome Plating in Clovis, Calif., just didn’t see it that way.

Ripple Effect: Researchers say leveling of electrodeposits can be achieved by applying a small forcing voltage
Seeking smoother plating deposits? It may be all in the waves. This story looks at studies that have shown that superimposition of a small sinusoidal potential wave (smooth, repetitive oscillation) onto a potentiostatic bias can lead to more level electrodeposits in finishing.
Read MorePlating on Tellurium Copper Alloys Plating on Tellurium Copper Alloys
I cannot achieve uniform adhesion of either Wood’s nickel or cyanide copper on C14500, tellurium-bearing copper. I clean using reverse current followed by 11 percent HCl, a Wood’s nickel strike and a silver strike. After stripping the failed plate and repeating the process, I sometimes have much better adhesion. Is this due to the aggressive etch provided by the stripping process or better oxide removal provided by the process?
Read MoreMore on Magnetic Parts
In the November 2011 issue of Products Finishing I briefly discussed problems with plating magnetic parts. One of my readers (also a student of mine some 25 years ago) sent me an email mentioning some other causes of parts becoming magnetic. One has to do with the machining and preparation of the parts.
