The corrosion of steel is an unavoidable problem for aging structures. One of the most common causes of corrosion is due to chlorides, as they are abundant in nature and have the ability to pass through the coating of stainless steel and allow corrosion to occur. With the large amount of infrastructure that is currently around, the cost to manually check and repair damage done by corrosion would cost billions of dollars. It is also difficult to know the amount of corrosion from the current methods of inspection, as they lack accuracy and require a large amount of time for professionals to travel and inspect each site. In some instances manual inspection is not an option, such as pipelines at the bottom of the ocean or other extreme and remote environments. In order to try to monitor corrosion, a sensor has been developed in order to find the electrical properties of steel as it is exposed to corrosion. These results will make it possible to remotely monitor the degree of corrosion that the sensor is attached to. This allows for the acquisition of data without the need for a site visitation, and thus more efficient and cost-saving.
