Abstract
The corrosion behavior of Ni-Cr-P-C alloys in which the Ni/Cr atomic ratio was fixed to unity was studied in connection with metallurgical structure by electrochemical measurement and X-ray diffraction. The Ni-Cr alloy was vitrifiable by the addition of 12 at% phosphorus, but was not by single addition of carbon. In 6N HCl at 30°C, both conventionally cast and melt-spun crystalline Ni-Cr alloys had low corrosion potentials less than -300mV (SCE) and showed high anodic current density of the order of 103 to 104A/m2 by anodic polarization. Once they were vitrified, they passivated spontaneously in the same aggressive solution and showed excellent corrosion resistance. The corrosion resistance of amorphous alloys was largely deteriorated even by a small amount of crystalline phase precipitation.
