Excellent

Excellent channel. The PCM data is difficult to interpret

Can we say if we have disbond coatings using this method?

[@isifundi]

PCM is not likely to identify disbonded coatings. In fact, none of the conventional coating integrity survey techniques will reliably detect disbonded coatings. It is a challenge.
