Abstract
A corrosion sensor and method for its use to detect and determine the, type, location, size and growth rate of corrosion of metals and the like in a corrosive environment. The corrosion sensor can distinguish between different types of corrosion such as uniform corrosion, pitting, crevice, and stress corrosion cracking. The sensor detects corrosion conditions of a corrodible metal article in a corrosive environment. It has a metal probe comprised of a metal which is substantially identical to that of the corrodible metal article and a transducer element attached to said probe, which is capable of projecting and receiving ultrasonic or radio frequency signals through the probe. The received signals indicate corrosion of the probe and hence the corrodible metal article.
