摘要 基于有限时域差分法研究太赫兹波在船舶防护涂层系统的传播特性。建立了太赫兹波在船舶防护涂层系统的脉冲检测模型,并进行了涂层系统中无缺陷和有缺陷情况的仿真研究。对多层结构涂层中各涂层厚度进行定量分析,并对涂层中存在的气孔、涂层氧化物等缺陷进行诊断分析。仿真结果表明,有限时域差分模型为基于太赫兹脉冲成像的船舶防护涂层系统的无损检测和评估提供理论支撑,有利于提供及时有效的维护措施以及涂层设计具有借鉴作用。 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.
