| Abstract Scope |
Corrosion is a huge economic and environmental concern for metal applications. Detecting and monitoring corrosion are imperative to prolong material life span, decrease the life-cycle cost, and reduce environmental impact. There are various methodologies for corrosion detection and monitoring which include, but are not limited to, ultrasonic, fiber optics, acoustics, and thermal imaging. These corrosion detection techniques exploit changes in structural, chemical, mechanical, thermal, electrical, and magnetic properties of metals to detect corrosion and calculate corrosion rate. This project focuses on developing 3-D printed Bluetooth microsensor to detect corrosion in steels used for oil and gas pipeline. The microsensor will detect the changes in magnetic and electric properties of the metal caused by corrosion, including resistance, impedance, conductance, magnetic permeability and magnetorestriction. Through the use of the microsensor, both uniform and localized corrosion can be detected, allowing for the understanding of the life-span and prevention of environmental damages. |
