The measurement methods are arranged and integrated in the network for reference only.

1、 Nondestructive method:

Magnetic thickness gauge is a non-destructive measurement method, which is usually used to measure the thickness of non-magnetic coating on iron-based base plate. If the coating thickness exceeds 10 microns, ultrasonic thickness gauge can be tried.

2、 Quasi nondestructive method:

If it is less than 10 microns, make a step in the micro part and use a step meter.

3、 X-ray fluorescence spectrometer

Now configure the background basic parameter method software to quantitatively analyze the thickness and composition of each coating.

Some netizens said that the thickness can be obtained by SEM or TEM.

I hope the above answers are helpful to your work. The information comes from network synthesis.
