Abstract
The pitting potentials of amorphous NixZ100-x powders formed by mechanical alloying of crystalline powder of the component elements which have different electrochemical properties were measured in 3.5% NaCl solutions in accordance with JIS G 0577.
From the results obtained it was found that the pitting potentials of the amorphous powders were more noble than the potential at which Ni dissolves actively, and less noble than the pitting potential of Zr. It was also concluded that the measurement of pitting potentials could be a useful method to follow the mechanism of the amorphous formation in mechanically-alloyed powders.
