A flow cell (with appropriate accessories) was developed for use in short-term testing of the corrosion behavior of materials in approx. 100/sup 0/C, hypersaline geothermal brine. An apparatus was designed to accommodate commercial (Petrolite) corrosion measurement equipment and to conduct experiments on-line at the Lawrence Livermore Laboratory Test Station in the Salton Sea Geothermal Field. The apparatus also permitted direct readings of corrosion potentials, solution redox potential (E/sub h/), brine flow rate, pH, and temperature. Estimates of general corrosion rates were obtained by the linear polarization resistance technique and from measurements of complete potentiodynamic polarization curves. Twenty-two alloys (with various heat treatments) were tested and readily grouped according to general corrosion resistances in acidified hypersaline (approx. 4 M chloride) brine.
