Research Initiatives for Materials State Sensing (RIMSS) Task Order 0020: High Frequency Eddy Current NDE

reportActive / Technical Report | Accession Number: ADA616524 | Open PDF

Abstract:

The study includes the development of a prototype system based on the EddyCusregistered Eddy Current device platform to characterize the thickness and electrical conductivity of wet conductive coatings. The prototype system includes special sensors for application on wet surfaces, electronics for Eddy Current measurements and laboratory software with algorithms to determine the coating thickness after complete drying. For method validation, an extensive sample preparation program was carried out. Two types of wet conductive coatings low and high conductive deposited at different thicknesses and with different coated areas on ceramic Al2O3 and carbon fiber-reinforced plastic CFRP substrates were investigated. Drying processes were analyzed under real conditions, i.e. drying under normal atmosphere, normal pressure and room temperature.
