Testing method for adhesion of electroplated nickel

--

Dear Sir,

We have a problem of testing the adhesion of the electroplated Ni layer. We would like to use a non-destructive testing method to test the adhesion strength of the coating.
The available destructive testing method, pull-off testing was suggested for this electroplated layer. But the polymer bonding between the electroplating and the testing assembly is not good compared to the adhesion of the electroplating and the substrate. So it is difficult to test the same using this.
Please suggest some ideas to test the same

Yours Truly,

Mr. Rajgopalan, I do not know a non-destructive test for nickel adhesion, but the simple destructive test is soldering a plug or a wire to nickel for pull testing.
