Non‐Destructive Coating Thickness Measurement

COATINGS are applied for a wide variety of reasons. These include atmospheric protection, appearance, performance, cost (coated material is often cheaper than the solid) and so on. Methods of application very much depend upon the coating being applied: spraying, dipping, electrolysis, chemical treatment and conversion, are all common methods. No matter what the coating or method of application, the monitoring and control of thickness is mandatory and if that control can be accomplished non‐destructively there are many additional advantages.
