“…Generally, there are several basic types of alloy additives: - Noble metals as a second phase composite, like Pd [ 36 , 126 , 127 ], Cu [ 73 , 128 ], Ag [ 125 , 129 , 130 ] cause local galvanic corrosion, because of their high electrochemical potential.
- The addition of silicon drew the attention of scientists because devices made of the Fe-Mn-Si alloy have shape memory and a higher corrosion rate [ 54 , 68 , 72 , 83 , 131 , 132 ].
- Elements from the second group, Mg and Ca, have strong negative electrochemical potentials (Mg = −2.38 V vs. SHE, Ca = −2.76 V vs. SHE).
