Comparative Study on Nondestructive and Destructive Methods of Evaluating Thicknesses of Hot-dip Galvanized Coatings
Two on-site nondestructive methods, one involving an electromagnetic thickness tester and the other a handheld x-ray fluorescence analysis system, were used to evaluate thicknesses of hot-dip galvanized coatings on steel and compared with destructive analytical methods. They were sufficiently applicable for measuring the remaining thickness or mass of the coatings when the density of the alloy layer or the zinc depth profile was already known.
