Abstract:

The organic coating deposited on a metallic substrate is quantitatively evaluated by measurement of electrical signals through an electrochemical cell having an electrode separated from the deposited coating by a porous pad within which a liquid medium is absorbed. Quality determining parameters of the coating are rapidly calculated through a data processor to which electrical current and phase shift measurements are fed together with data from the electro-chemical cell. The method may be used to evaluate the quality of the coating on the steel hull of a marine vessel exposed to seawater.
