Ionic Liquid Plating
Can ionic liquid plating be used as a replacement for conventional plating?
Read MoreZinc Plating and Crystal Growth
We are running a potassium chloride zinc plating bath. The bath has heavy crystal formation throughout and a very thick layer of sludge at the bottom of the tank. As you might guess, we are not obtaining satisfactory plating from the bath.
Read MoreWhere's the Copper Coming From?
We use a cyanide copper strike bath in a couple of our plating processes. Over time the copper concentration increases in the bath. Why?

I am looking for a quick test to determine if a nickel plate has been completely removed from a steel substrate.

Dull Zinc Plating
We zinc plate many batches of parts each day. Some of these batches come out dull after the plating and chemical conversion steps. Could this be caused by the base material?
Read MoreFiltration Basics
I need some basic information on filtration in the plating shop. My major concern is sulfate copper and Watts nickel.
Read MoreMagnetic Moments
The plating shop says the parts are magnetic when they receive them and the machining operation says they are not magnetic when shipped to the plater.
Read MoreReminder: Blame the Weather
This summer we had a number of days when our plating processes did not seem to work properly. Some days our production would go well with no problems, and other days we were tearing our hair out trying to resolve such things as water spots and other defects. I have been in the plating business for nearly 30 years and suggested that some of the problems have to do with the strange weather we experienced on the East Coast.
Read MoreFailure of Zinc Plating
Our company produces steel components that are welded and sent out to a plating vendor for zinc plating and a trivalent chromium chemical conversion coating. On some of these parts, the zinc plate deteriorates after short periods of storage. Corrosion appears along welds and close to the weld areas.

Is it possible to put black oxide over cadmium plate? Will the cadmium plate be degraded by the black oxide solution? Will the black oxide solution be degraded by exposure to cadmium?
