This paper will present a detailed study on corrosion current and corrosion behavior using electrochemical technique. The corrosion rates of different alloys and metals in a test liquid of blow down water collected from an oil field boiler were measured. The working electrode was made from the alloy/metal material using a cold mount epoxy and the corrosion rates of the alloys/metals were compared. The effects of a corrosion inhibitor and pH value on the corrosion behavior were investigated. The electrochemical method provided reproducible test results and a time efficient way for corrosion rate measurement.
