CORROSION SENSORS

摘要

A corrosion sensor comprises an insulating substrate,a thin film of a first metallic material formed on the substrate; and an array of areas comprising a second metallic material provided at the surface of the thin film. A method for manufacturing such a sensor is also disclosed. An exemplary embodiment is disclosed in which the thin film is patterned to define a number of tracks, the resistance of which can be monitored in order to determine the degree to which the thin film has corroded.
