Abstract

The long-term corrosion behavior of test pieces and cooling plate of laser additive manufactured AlSi10Mg Al-alloy in commercial ethylene glycol coolant was assessed via isothermal test at 88 ℃ and thermal cyclic test, meanwhile the degradation of ethylene glycol coolant was examined along with the corrosion process. The results showed that the pH value and reserve alkalinity of the coolant decreased with the increasing time, while the content of Al ions, mechanical impurities, and acidic oxidation products of ethylene glycol in the coolant increased, and glyoxylic acid was the main acidic oxidation product of ethylene glycol. The monitoring parameters of coolant degradation displayed different trends in thermal cycling test and constant temperature test, with a clear time turning point in thermal cycling test, and the corrosion rate of aluminum alloy in thermal cycling test was significantly higher than that in isothermal test. The corrosion products on the surface of Al-alloy were composed of Al₂O₃, Al-ethylene glycol, Al-ethylene glycol oxidation products, and precipitates of corrosion inhibiting components.

Key words: coolant laser additive manufacturing Al-alloy ethylene glycol degradation corrosion
