- Abstract
- An under deposit corrosion test method has been developed where three carbon steel specimens are mounted together in an assembly. Two of the specimens are covered by sand or another deposit, while one specimen is not covered. The potential difference and galvanic current between sand covered and not covered specimens is measured. The corrosion rate of all three specimens is measured by linear polarization resistance measurements, while the galvanic current is measured by zero resistance ammetry. The paper summarizes the test method and presents experience in using the test method for both film-forming inhibitors and pH stabilization. ©NACE International. All rights reserved.
