I need to measure the coating thickness of Aluminide in the range of 50 to 100 microns with an accuracy of + / - 10 microns. ANy ideas and past experience will be helpful.    Reply  Translate  Close   RON PRESTON RON PRESTON 03:08 Feb-10-2000 Re: Measurement of coating thickness : TRY USING EDDY CURRENT INSPECTION.

THE METHOD IS MADE FOR THIS PURPOSE. I have almost the same problem, I'm doing thickness measurement of NiAl on Inconel 600 for my final year project. I've tried eddy current, it doesn't help much. The signal was too weak. But still, maybe anybody can specify more on that, I mean what are the machine capabilities, sample requirement, etc. Thank you    Reply  Translate  Close
