Corrosion Performance of Cu-Based Coins in Artificial Sweat by J. Porcayo-Calderon, R. A. Rodríguez-Díaz, E. Porcayo-Palafox, L. Martinez-Gomez

“…Equivalent circuits confirmed that the corrosion performance of the Ni-Zn-Cu coins depends on the Zn/Ni ratio, such that decreasing this value decreases the corrosion resistance of the alloy. In general, nickel has a detrimental effect due to the formation of highly soluble Ni-based corrosion products.…”
