Development of Eletrical Resistance Based Corrosion Rate Sensor

This report describes the work done on investigating the change of electrical resistance of copper wires in a corroding solution. The work was carried out as part of a project to develop a miniaturized electrical resistance based corrosion rate sensor. This work will be carried out by using three different thicknesses of copper wires. The experimental measurement will be done to investigate the change in electrical resistance of each wire in corrosive agent. The corrosive agent used is 3.5% salinity of water which is typically used in corrosion study. For the literature review, description of corrosion itself will be introduced first. This is followed by a brief description of Electrical Resistance(ER) technique to monitor corrosion. At the end of this report, some findings and data collection out of this work are discussed. Finally, the conclusion of the work done is included together with some recommendations for future work.
