Abstract

The invention provides a method and apparatus intended to allow accurate monitoring of the corrosion behaviour of material when exposed to an environment. The method and apparatus are based around the field signature method. The invention particularly includes a method of investigating corrosion of a material in a given environment, the method including manufacturing a test sample from a sample of the material, providing two or more electrical contacts in contact with an internal surface of the test sample, providing an external surface of the sample in contact with the environment, measuring the voltage between two or more electrical contacts at a first time and at one or more other times, an external surface of the sample being in contact with the environment during one or more of the times, a current being passed through the sample at the time of the voltage measurement, the voltage measurements providing information about the effect of the environment on the sample with time, and wherein the internal surface of the sample on which the electrical contacts are provided is physically isolated from the environment during the voltage measurements by a seal.
