Non-magnetic metallic coatings on metallic and non- metallic basis materials. Measurement of coating thickness. Phase-sensitive eddy-current method Ingestion-build-54484 equipment inspection requirements1 Scope This document specifies a method for using phase sensitive eddy current instruments for non destructive measurements of the thickness of non magnetic metallic coatings on metallic and non metallic basis materials such as: a) zinc, cadmium, copper, tin or chromium on steel; b) copper or silver on composite materials. The phase sensitive method can be applied without thickness errors to smaller surface areas and to stronger surface curvatures
