Electrochemical Studies of Geothemal Corrosion

Abstract

to monitor the plant or to guide the selection of materials and operating conditions in the design plant. number of methods have successfully used to measure corrosion rates in geothermal they include weight-loss method, the (resistance probe), the hydrogen probe, stress corrosion rigs and other methods Electrochemical techniques have been widely used, although they appear to be quite advantage of methods is that they provide a direct measurement of the corrosion rate and it is possible to distinguish between active corrosion and passivation of the metal surface. Corrosion testing geothermal systems normally carried out A We have a research project using electrochemical and related methods to determine the mechanism of corrosion of steel and other metals in geothermal fluids from the Broadlands field. paper some of our initial findings.
