TIME DOMAIN DIAGNOSIS OF ANTICORROSION COATINGS VIA SHAPE DESIGNED MEASUREMENT SIGNALS

Romuald Zielonko, Marek Niedostatkiewicz

Abstract

The paper presents time domain diagnostic method of anticorrosion coating on the level of equivalent circuit parameter identification. The method is based on applying non-conventional, shape-designed stimuli signals and measuring the object responses (so-called observables) at a given time T. Equivalent circuit parameters are calculated directly from observables using analytical equations, determinated by modelling circuit topology. In the paper the theoretical basis of the method is presented, together with measurement methodology and simulation results for 4 elements anticorrosion coating equivalent circuit.
