Corrosion characterisation of coated steel involves various approaches via non-destructive testing (NDT) and structural health monitoring (SHM) techniques. This paper evaluates and discusses the application of the recent development of a portable lamp-pulsed thickness tester and commercial off-the-shelf (COTS) ultra-high-frequency (UHF) radio-frequency identification (RFID) sensing. The findings affirm the efficacy of the portable lamp-pulsed thickness tester and COTS UHF RFID sensing for corrosion characterisation. Furthermore, these methods are compared with other non-destructive testing and evaluation (NDT&E) and SHM techniques such as pulsed eddy current (PEC), eddy current pulsed thermography (ECPT), low-frequency (LF) RFID and chipless RFID sensing and monitoring. This study compares the principles, merits, limitations and accuracy of different corrosion characterisation approaches and discusses their future development.
