Methods and devices for electrochemically determining metal fatigue status

摘要

Devices and methods for determining the fatigue status of a metallic specimen are provided. The methods utilize the devices, which are an array of a number of cells or modules. Each cell in the array has an electrode, and an electrolyte in contact with a surface of the specimen. The cells of the array can determine a relative fatigue status of a large surface area of the specimen of interest.
