“…Nowadays, in addition to the development of efficient corrosion protection technologies, timely and effective corrosion monitoring and detection technologies are also particularly important. For example, resistance probe technology, , fluorescence probe technology, ultrasound monitoring technology, field fingerprint online wall thickness monitoring technology, , nondestructive diagnosis pulse eddy current technology, etc., provide an important basis for scientific management and decision-making. On the one hand, these technologies can be used to monitor the corrosion status of the medium, identify problems in a timely manner, and prevent the occurrence of major accidents.…”

Corrosion has always been a major issue that restricts social development. The global annual corrosion cost is 2.5 trillion U.S. dollars (approximately 3.4% of the world's gross domestic product). Corrosion can also cause resource waste, environmental pollution, and major safety accidents. In recent years, researchers have utilized various corrosion prevention and control technologies and materials to protect metals and other materials from corrosion and achieved gratifying results. Among them, carbon materials have been applied in anticorrosion treatment due to their unique physical and chemical properties, low price, and environmental friendliness. This review mainly summarizes the structure of carbon-based nanomaterials (such as graphene, graphene oxide, reduced graphene oxide, carbon nanotubes, carbon quantum dots, carbon fiber, graphite, etc.) and their applications in corrosion prevention as coating, corrosion inhibition, photocathodes, etc. It focuses on the current research status and corrosion resistance mechanism of carbon materials such as graphene, graphene oxide, carbon quantum dots, and carbon nanotubes in the field of corrosion prevention and control.

“…As for remotely detecting elastic waves propagated through concrete, non-contact acoustic systems with a laser doppler vibrometer (LDV) for detecting signals have been reported [13][14][15]. These research approaches provide remote and rapid operations for inspection works based on the elastic wave method.…”

In this study, to visualize damage and defects, such as cracks and voids in concrete, the SIBIE (stack imaging of spectral amplitudes based on impact echo) procedure is applied and numerically improved to construct a three-dimensional (3D) model of elastic wave propagation behavior. A unit of arrayed accelerometers is installed to detect multi-channel signal waveforms in the frequency domain. The resonant frequencies due to reflections at each node in 3D lattice nodes are computed by using the distances from elastic wave input to multiple output locations. The amplitudes corresponding to the resonant frequencies in the spectrum are summed up as the reflection intensity of elastic wave at each node. The reflection intensity distribution is visualized finally in the targeted area three-dimensionally. Case studies are carried out on the proposal of the improved 3D-SIBIE procedure, applied to a concrete specimen with simulated-damage as well as in-situ highway RC (Reinforced Concrete) slabs in service. As for the signal detection, a non-contact elastic wave detecting system using a laser doppler vibrometer is also introduced to consider and validate the promising remote sensing and inspection technique for damage evaluation in concrete with the 3D SIBIE procedure.

For a non-contact, non-destructive quality evaluation, laser ultrasonic testing (LUT) has received increasing attention in complex manufacturing processes, such as additive manufacturing (AM). This work assessed the LUT method for the inspection of internal hole defects in additive manufactured Ti-6Al-4V part. A Q-switched pulsed laser was utilized to generate ultrasound waves on the top surface of a Ti-6Al-4V alloy part, and a laser Doppler vibrometer (LDV) was utilized to detect the ultrasound waves. Sub-millimeter (0.8 mm diameter) internal hole defect was successfully detected by using the established LUT system in pulse-echo mode. The method achieved a relatively high resolution, suggesting significant application prospects in the non-destructive evaluation of AM part. The relationship between the diameter of the hole defects and the amplitude of the laser-generated Rayleigh waves was studied. X-ray computed tomography (XCT) was conducted to validate the results obtained from the LUT system.
