Anticorrosion properties of antifreeze of internal combustion engine cooling system

Khodyakov A.A., Bernatskiy V.V., Fedoseyenko Y.Y.


Anticorrosion properties of carboxylated antifreeze are investigated. It is found that long-time contact between coolant liquid and steel changes neither surface condition of specimens nor mass of them. It is demonstrated that steel surface under electrochemical corrosion conditions can in some cases take on the property of anticorrosion barrier.
