Abstract

Corrosion costs are above 3.3 trillion US $ worldwide affecting infrastructure such as highways, bridges, buildings, oil pipelines and industrial machining. Corrosion so far has severe consequences like down times, maintenance costs and security issues. Concerning lubricants a lot of research has been carried out the last decades by manufacturers of machines and lube formulators to protect metals against corrosion but each time a formulation is changed because of legislation, raw material availability or technical justifications, costly long term field tests most often have to be performed. Electrochemical Impedance Spectroscopy (EIS) is a method at the forefront of technology that supports the lubricant and metal industry identifying potential challenges of lubricant corrosiveness, corrosion tendencies of metals and additive performance.
