Abstract

Abstract: The propagation of terahertz radiation in marine protective coatings was investigated based on Finite-difference time-domain method. The theoretical framework using terahertz waves for the detection of marine protective coatings was established; also, both intact and defected coating system were modelled and analyzed. The reflected radiation properties were recorded for quantitative characterisation of marine protective coating thickness. Furthermore, diagnostic analysis was done for the defects of the coating system, such as bubbling and oxidation of rust. The Finite-difference time-domain model provides some theoretical basis for nondestructive testing and evaluation of marine protective coating system by terahertz pulsed imaging technology and will benefit the effective maintenance to avoid coating failure and for protective coating design.
