Abstract:
Solutions of ethylene glycol are being considered as beat-transfer media for radiators in manned space capsules. This report was prepared to summarize the available corrosion data on uninhibited and inhibited ethylene glycol solutions. Much of the corrosion data are based on automotive and diesel engine coolant systems. Several factors considered are time dependence, effect of pH, concentration, temperature, aeration, chloride ion, velocity, heat- transfer rate, and galvanic couples. Inhibitors for which corrosion data are presented include borax, sodium benzoate, sodium nitrite, triethanolamine, Sodium mercaptobenzothiazole, soluble oil, chromates, as well as miscellaneous inhibitors. A number of patented inhibitors based on borax are discussed. Descriptions of test procedures including automobile service tests are presented.
