摘要：
Using the method of mathematical design of experiments, we have studied the influence of ethylene glycol concentration and temperature over a wide range of their variation on the corrosion of AMg3 aluminum alloy. We have established that, irrespective of the ethylene glycol concentration, the maximum corrosion losses are observed at temperatures of 60–70°C. The inhibiting action of ethylene glycol at concentrations exceeding 40% is caused by an increase in the viscosity of the solutions and by the formation of slightly soluble surface complexes of aluminum with ethylene glycol and the products of its oxidation.
