surface inspection beneath plating

We have a requirement to perform a PT inspection the sealing surface of a NiCu plate on a periodic basis. To restore the surface finish due to damage, the plate was electroplated w/ copper. The question is - Are there any alternate NDT inspections to verify that the base plate surface beneath the plating is free of defects or will the plating have to be removed and the PT inspection performed?

look into UT longitudional wave inspection for a bond no bond application

Re: surface inspection beneath plating Hi I'm not quite familiar with the NiCu plate you metntion but according to conditions you specify, have you ever consider the possibility to use Eddy current or MT in case it is magnetic? You must be aware about the copper plating thickness in any case and probably will have to qualify test procedure with reference discontinuity block so you can understand how indications from defect may look like
good luck in any case with your inspection

Re: surface inspection beneath plating whats is the thickness of the copper ? you may be able to use MT inspection depending on the thickness of plating, alternatively is eddy current.

Re: surface inspection beneath plating (UT thickness gauge) UT thickness gauge machine is alternative option for you. Calibrate dissemination of waves according to your metal. corrosion and reduced sections can be best detected even debounds.

Hi Joe,

I emailed you with some suggestions with regard to this inspection.

Steve
