    Abstract:
    The corrosion characteristics of some selected types of aluminum in uninhibited ethylene glycol/water solutions have been studied under conditions relevant to the operation of aluminum solar heat collector systems. Measurements of linear polarization resistance and maximum pit depth were used to assess the extent of corrosion activity. Pure aluminum (99.9%) as well as 1100 (commercially pure aluminum) and 3000 (~1% Mn) series alloys were studied in aqueous solutions of 35 v/o (volume percent) reagent grade ethylene glycol. The investigation covered the temperature range from ~25% to 100°C. The corrosion behavior of these aluminum compositions were determined under various hydrodynamic conditions and in the presence of dissolved oxygen, common water contaminants, and ethylene glycol thermal decomposition products
