Q. Regarding anti-tarnish applied to copper plating --
A customer returned some pieces that have an oxidized area or some reaction over the surface.
These pieces were sent from North America to China and could be sent by ocean.
I am looking for an option to prove that our plater/supplier applied the correct thickness of anti-tarnish.
How can I measure the film of anti-tarnish?
My drawing only states apply anti-tarnish over the plated surface.
I appreciate any feedback about this topic.

Q. After copper plating I am doing anti-tarnish on copper plating as follows: prepared a solution of sodium dichromate and phosphoric acid 5% in water; dipped copper plated component in above solution for 1 min.

Now I want a method for detection of copper phosphate because after immersing copper plated component in above solution a copper phosphate film formed on component.

A. Hi, Ajay.

Unfortunately, your question isn't really answerable. On the one hand, if no one is requiring you to test it, you don't have to test it :-)
But on the other hand, if you are copper plating the steel, it is because the plating is intended to fulfill some function . . . and if it is intended to fulfill some function, you have to test it to make sure that it is doing so.

Corrosion testing via salt spray is only one of many corrosion tests, and corrosion prevention is not the reason for the copper plating. You must answer for yourself the question: "Why are we copper plating it?" before you can ask any questions about testing.

Luck & Regards,
