Corrosion detection (CD) has become a high priority in chemical industries, defense and transportation sectors to extend the life of existing or new systems while ensuring the safety of the existing components and reducing downtime to minimise economic losses. Here, this article is aimed to review and discuss non-destructive techniques used widely in the industry to detect, monitor and repair corrosion problems early on. The comprehensive review provides a detailed discussion, a functional mechanism, advantages and disadvantages of crucial non-destructive CD techniques widely used in the industry, helping the reader choose the type of corrosion monitoring methods effectively. An extensive literature review of visual and optical testing techniques, acoustic emissions, eddy current, guided wave and equipment, infrared thermography, radiographic, microwave and millimeter wave, and terahertz imaging is discussed. The underlying mechanism, its merits and limitations, along with the usage scenario, is explained that can be related across different areas making it interdisciplinary research for corrosion monitoring techniques.

“…However, some works have considered "V" and tilted crack models as well [45], [55]. Some of the recent literature has reported a crack model which consists of a cut with certain width and depth (see [52], [59], [60], [61], [62], [72], [74]). However, the representativeness of such a model when the length of the cut is a good portion of the wavelength was not thoroughly established, and qualification of the methods which adopted such a model on real crack samples was not reported in the literature.…”

“…Today, there is a wide range of microwave and millimeter-wave crack detection and characterization methods. The majority of the reported methods are categorized in this article as far-field [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], near-field [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51], [52], [53], [54], [55], [56], [57], [58], [59], [60], [61], [62], [63],…”

Integrity assessment of metallic structures requires inspection tools capable of detecting and evaluating cracks reliably. To this end, many microwave and millimeter-wave nondestructive testing and evaluation (NDT&E) methods have been developed and applied successfully in the past. Detection of fatigue cracks with widths less than 5 µm using noncontact microwave-based inspection methods was demonstrated in the 1970s. Since their introduction, these methods have evolved considerably toward enhancing the detection sensitivity and resolution. Undertaking key application challenges has attracted considerable attention in the past three decades and led to the development of the near-field techniques for crack detection. To address a need that cannot be fulfilled by other NDT&E modalities, innovative noncontact microwave and millimeter-wave NDT&E methods were devised recently to detect cracks of arbitrary orientations under thick dielectric structures. While the reported methods share the same underlying physical principles, they vary considerably in terms of the devised probes/sensors and the application procedure. Consequently, their sensitivity and resolution as well as their limitations vary. This article reviews the various crack detection methods developed to-date and compares them in terms of common performance metrics. This comprehensive review is augmented with experimental comparisons and benchmarking aimed to benefit NDT&E practitioners and researchers alike.

“…Chen G et al designed two TEM-TM01 and TEM-TM02 incident probes to obtain better propagation mode purity and propagation directionality, detect defects in different orientations, and analyze the influence of propagation mode conversion at bends on detection signals [19][20][21][22]. YU YT et al established a finite integral numerical model to analyze the relationship between the reflection coefficient phase and the defect edge position [23]. Experts and scholars have analyzed the relationship between microwave intrinsic impedance, defect position, and wavelength, but they have not specifically analyzed the relationship between microwave defect signals and defects.…”

With the aim of addressing the difficulty of detecting metal surface cracks and corrosion defects in complex environments, we propose a detection method for metal surface cracks and corrosion defects based on TE01-mode microwave. The microwave detection equations of cracks and corrosion defects were established by the Maxwell equations when the TE01 mode was excited by microwaves, and the relationship model between the defect size and the microwave characteristic quantity was established. A finite integral simulation model was established to analyze the influence of defects on the microwave electric field, magnetic field, and tube wall current in the rectangular waveguide, as well as the return loss at the defect; an experimental platform for the detection of metal surface cracks and corrosion defects was built. The absolute value of the return loss of the microwave reflected wave increased, and with the increase of the defect width, the microwave detection frequency at the defect decreased. The TE01-mode microwave has good detection ability for metal surface cracks and corrosion defects and can effectively detect cracks with a width of 0.3 mm.
