Patent ID: 7763125

Claim:
An amorphous alloy represented by the formula: Fe 48 Cr 15 Mo 14 Er 2 C 15 B 6 and wherein for a test duration said alloy is exposed to an environment having a designated pH level, said alloy is determined to have a differential voltage, V, wherein differential voltage, V, equals E pit −E oc , wherein E pit is pitting potential and E oc is open circuit potential, wherein: said alloy has a voltage differential, V, that is determined to have at least one of the following magnitudes: if said PH level is equal to about 1.0, then V is equal to about 0.710 if said PH level is equal to about 6.5, then V is equal to about 0.883 and if said PH level is equal to about 11.0, then V is equal to about 1.129.
