Surface roughness

Dear collegues,

I am trying to do surface roughness characterization with eddy current probe. Can you advise me about one method that can do this.

Thanking you in advance

Patrick

Patrick,
We have developed a system using stress waves that can differentiate between different roughness levels. If you can contact me I can discuss the system further.

We have developed and used ultrasonic system to measure surface roughness on plates and parts during turning. The system also can measure parts thicknesses in micron accuracy and also measures surface integrity and stresses. If you are interested please contact us at above email.
