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

 
A. This question comes up from time to time. There are sophisticated instrument-based methods that you can use to determine the presence of nickel on a substrate. However, sometimes a simple, straightforward test will give you an answer. In this case, the simplest way to make a determination is to dip the part in a copper sulfate solution. An immersion deposit of copper will form on bare steel. Areas with nickel on the surface will not form a copper immersion deposit. The deposit can be wiped off after the test.
