Evaluation of inhibitors blends used in Iraqi markets for automobile cooling system

الملخص EN

Detection the behavior of some metals ( carbon steel and copper) that are widely used in automobiles cooling system in tap water and a cooling mixture for radiators was held.

The purpose of this work is to check the performance of two types of mixtures that available in Iraqi markets, viz the Kuwait mixture and the Germany one and what are known as blue water by an electrochemical technique.

The experiments were held at two values of temperatures of 17 and 80 ˚C-where these values of temperature almost represent the cases of idle and operating engine.

The obtained results showed that the two types of mixtures have given good inhibition efficiency for the case of steel especially in presence of Germany mixture.
