We have chromium stripped from some components for rework. Is there a test to determine if all the chromium has been removed?

TIA

RE: test for chrome after stripping operation

Um. That is an alloy with about 1.5% Chromium content by design, not sure you will be able to "strip" it of chrome without dissolving the part in acid, at which point the part is gone...

RE: test for chrome after stripping operation

A copper sulfate solution is commonly used to show presence or absence of plating after a stripping operation on ferrous substrates. In the absence of plating, the copper sulfate will "plate out" copper on the substrate. The copper can then be removed after the test with house hold ammonia
