Corrosion properties of a bulk Cu0.5NiAlCoCrFeSi glassy alloy such as electrochemical corrosion potential (ECP), potentiodynamic polarization, and weight loss measurements were carried out for the first time in 288 degrees C high-purity (outlet conductivity <0.07 mu S cm(-1)) water. The change of ECP with dissolved oxygen (DO) showed a sigmoid curve. In addition, the Cu0.5NiAlCoCrFeSi alloy exhibited a wide passive region and the passive current density was similar to 2 x 10(-4) A cm(-2) in deaerated water containing 0.01 N sodium sulfate (Na2SO4) at 288 degrees C. A very low weight loss of similar to 4.5 mu g mm(-1) was also found for the Cu0.5NiAlCoCrFeSi alloy after immersion in deacrated 288 degrees C water for 12 weeks.
