Must we do MPI/FPI on surface treated fasteners?

March 7, 2008

We are doing electroplating for aerospace grade articles. I would like to know whether it is advisable to carry out Magnetic Particle testing and Flauroscent penetrant testing of the items after electroplating (Cd, Hard Chrome, Zinc, Cu etc.)/ Conversion coating (Zn Phosphating). The items are mainly Fasteners.

Please advise.

Thanks in advance.
