Low-Cost Technologies Used in Corrosion Monitoring

Abstract

Globally, corrosion is the costliest cause of the deterioration of metallic and concrete structures, leading to significant financial losses and unexpected loss of life. Therefore, corrosion monitoring is vital to the assessment of structures’ residual performance and for the identification of pathologies in early stages for the predictive maintenance of facilities. However, the high price tag on available corrosion monitoring systems leads to their exclusive use for structural health monitoring applications, especially for atmospheric corrosion detection in civil structures. In this paper a systematic literature review is provided on the state-of-the-art electrochemical methods and physical methods used so far for corrosion monitoring compatible with low-cost sensors and data acquisition devices for metallic and concrete structures. In addition, special attention is paid to the use of these devices for corrosion monitoring and detection for in situ applications in different industries. This analysis demonstrates the possible applications of low-cost sensors in the corrosion monitoring sector. In addition, this study provides scholars with preferred techniques and the most common microcontrollers, such as Arduino, to overcome the corrosion monitoring difficulties in the construction industry.

Corrosion Monitoring by Plastic Optic Fiber Sensor Using Bi-Directional Light Transmission

“…In addition, a USB camera (6) was positioned above the observation boreholes and left open to capture images at the bottom of each observation hole. Moreover, device (4) was configured to supply DC for the electric corrosion test, and an electric circuit was established by connecting the electrodes from this device to the steel plate and a stainless-steel plate submerged in the brine (5). Light from a white LED light source (1) (refer to Figure 22a for details) was directed to the SUB-1 fiber of each R2S sensor.…”

“…Previous studies have delved into the corrosion process and monitoring technologies across various fields, aiming to provide a comprehensive overview [4,5]. These studies sought to assess corrosion initiation and progression by monitoring key factors influenced by corrosion onset, including physical appearance [6], alterations in electrochemical signals [7][8][9][10][11], specimen weight variations [12], structural deformation [13][14][15], alterations in wave propagation characteristics [16][17][18][19], and modifications in the biological corrosion environment [20].…”

Iot-Based Solution for Detection Defects in Infrastructure Objects Using Raspberry Pi

“…Using the Internet of Things to process data on the state of corrosion and concrete to send to cloud storage [2,3], but the main detection method is external sensors. Paper [4] provides a detailed literature analysis on low-cost sensors and the possibilities of their use for corrosion monitoring. Such an analysis is important for evaluating the possibility of the described integrated approach for detecting defects in various types of objects.…”

Expansion Joints Risk Prediction System Based on IoT Displacement Device

“…It can be divided into corrosion inspection and corrosion monitoring [6]. Corrosion monitoring measures the damage of corrosion and the variables that accelerate the rate of corrosion over a long period, and it has received much attention as a means of ensuring the safe operation of structures in various industries [7]. The method of identifying structural systems is an important component of SHM, which evaluates the parameters of structural models [8].…”
