Abstract
Disclosed are various embodiments related to a corrosion detection device for detecting corrosive environments. A corrosion detection device comprises a magnetic sensor and at least one magnetic nanowire disposed on the magnetic sensor. The magnetic sensor is configured to detect corrosion of the one or more magnetic nanowires based at least in part on a magnetic field of the one or more magnetic nanowires.
Claims20
A corrosion detection device, comprising:
- a magnetic sensor;
- and
- one or more magnetic nanowires disposed on the magnetic sensor, wherein the magnetic sensor is configured to detect corrosion of the one or more magnetic nanowires based at least in part on a magnetic field of the one or more magnetic nanowires.
A method for detecting corrosion, the method comprising:
- placing one or more magnetic nanowires on a magnetic sensor to form a corrosion detection device;
- attaching the corrosion detection device to a material structure;
- obtaining one or more outputs of the magnetic sensor;
- determining corrosion of the one or more magnetic nanowires based at least in part on the one or more outputs, wherein a magnetization of the one or more magnetic nanowires decreases as the one or more magnetic nanowires corrodes;
- and
- determining that a surrounding environment of the material structure is a corrosive environment based at least in part on the corrosion of the one or more magnetic nanowires.
