remote Corrosion Monitoring of the rc structures using the electrochemical wireless energy harvesting sensors and networks
Ndt & E International, 2011Co-Authors: Guofu Qiao, Jinping Ou, Yi HongAbstract:Abstract Essentially, the Corrosion process of the steel bar in reinforcing concrete structures is a series of electrochemical reactions. Therefore, the released energy during these reactions provides the opportunities to identify the Corrosion status and power the wireless Corrosion Monitoring sensors. Furthermore, the recognition of the Corrosion status has been realized with active Monitoring techniques (AMTs) and passive Monitoring techniques (PMTs). Additionally, the sensor mote platform that harvests the Corrosion energy has been designed for Corrosion Monitoring, and then how to network these sensors to remotely access the Corrosion data has been discussed. The preliminary experiment has been conducted to validate the micro Corrosion energy.

Optimization Design of a Corrosion Monitoring Sensor by FEM for RC Structures
IEEE Sensors Journal, 2011Co-Authors: Guofu Qiao, Yi Hong, Jinping OuAbstract:Structural health Monitoring techniques provide the scientific basis for damage early-warning, safety assessment and maintenance design of reinforcing concrete structures. Solid-state and current confining Corrosion sensor, the key hardware component in Corrosion Monitoring system based on electrochemical theory for reinforcing concrete structures, is investigated here. The finite-element method is applied to simulate the distribution of the electric field in concrete and optimize the geometric configuration of the sensor. The simulation results indicate that the electric field can be confined accurately in a fixed region by the optimized Corrosion sensor.

Corrosion Monitoring Sensor Networks With Energy Harvesting
IEEE Sensors Journal, 2011Co-Authors: Guofu Qiao, Bin XuAbstract:Reinforcing concrete (RC) structures are applied extensively in civil engineering. The Corrosion of RC steel, often called the cancer of the steel, however, deteriorates the durability of RC structures greatly and then degrades the serviceability severely. The usage of sensors in the RC Corrosion Monitoring is one potential method where two problems have to be carefully considered. First, the long-term power provision of sensor is very hard to be implemented in microsensor systems; second, the data delivery of Corrosion Monitoring ought not to impact the original structure where sensors are embedded. In this letter, we discuss and design a framework of energy-harvesting sensor network to monitor the steel Corrosion in RC structure. Our framework provides insights about the Corrosion-Monitoring sensor system to store its ambient energy, and about effectively exploiting wireless sensor network to deliver the Corrosion data to the end user.

Investigation of pitting Corrosion Monitoring using field signature method
Measurement: Journal of the International Measurement Confederation, 2016Co-Authors: Fangji Gan, Zhengjun Wan, Gui Yun Tian, Junbi Liao, Wenqiang LiAbstract:The field signature method (FSM) is a nondestructive testing (NDT) method based on the potential drop (PD) technique and has been applied to online metal pipe Corrosion Monitoring for nearly three decades. The many advantages and benefits of the method have been reported in a number of studies, but few have reported on its limitations or shortcomings. However, the detection accuracy for pitting Corrosion in FSM is very low. In this paper, the reasons for the low pitting Corrosion detection accuracy of FSM were analyzed and it was found that different Corrosion pits, which have different sizes, depths or positions, generally have differing influences on the potentials of nearby electrode pairs. Therefore, a new method using a subdivided resistor network to assess pitting Corrosion is proposed and verified. When compared with the traditional method, the most important parameter, namely the pitting Corrosion depth detection accuracy, can be significantly improved.

Design of Hanford Site 4th Generation Multi Function Corrosion Monitoring System
2000Co-Authors: E.c. NormanAbstract:This document describes the design of the fourth-generation Corrosion Monitoring system scheduled to be installed in DST 241-AN-104 early in fiscal year 2001. A fourth-generation multi-function Corrosion Monitoring system has been designed for installation into a DST in the 241-AN farm at the Hanford Site in FY 2001. Improvements and upgrades from the third-generation system (installed in 241-AN-105) that have been incorporated into the fourth-generation system include: Addition of a built-in water lance to assist installation of probe into tanks with a hard crust layer at the surface of the waste; and Improvement of the electrode mounting apparatus used to attach the Corrosion Monitoring electrodes to the stainless steel probe body (new design simplifies probe assembly/wiring). These new features improve on the third-generation design and yield a system that is easier to fabricate and install, provides for a better understanding of the relationship between Corrosion and other tank operating parameters, and optimizes the use of the riser that houses the probe in the tank.
