How to measure Ni coating thickness on brass
How to measure Ni coating thickness on brass
(OP)
Dear all,
I am coating Brass parts with high P Ni.
Coating is about 7 to 10 micrometers.
Is there a technique/tool I can use to measure the the thickness?
So far I have been cutting them and use an SEM... Which is expensive...
Thanks,
Herc.

Well, we also have variation in our casting so that wouldn't be very accurate.
Salmon2,
We use an outside supplier for the coating so we want to have an easy check on his consistency. He has been unreliable in the past.
I like IRstuff's idea. I am going to look into it today, see how much the equipment costs.

There are hand-held devices based on non-destructive principles (ultrasonic, eddy current) that can measure this type of combination. Here is an example of one:
