Corrosion Inhibitors for Water–Glycol Based Cooling Systems

Abstract

The distinguishing features of the corrosion of automobile cooling systems, which contain a host of electrochemically diverse metals and alloys (copper, brass, solder, steel, cast iron, aluminum, etc.), operate at high temperatures and pressures, and are also subjected to corrosion and cavitation, are examined. The preferred corrosion inhibitors are determined by taking into account the mechanisms of corrosion in the cooling system for each type of metal.
