A corrosion sensor includes an insulating substrate, a thin film of a first metallic material formed on the substrate; and an array of areas what includes 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.

Corrosion sensors

The pelletisation or granulation of a material or mixture of materials the or at least one of which is reactive in a liquid to produce a gas is improved by treating the reactive material prior to final compaction to form a coating thereon of a substance which is less soluble in the liquid than the reactive material. The preferred reactive material is calcium hydride and the preferred coating is calcium carbonate with or without calcium hydroxide.
