摘要	Corrosion is a long-standing issue for engineering applications of copper-nickel alloys. Herein, cathodic acceleration and heterogeneous nucleation microalloying design strategies are proposed and validated to address this issue. The results show that microalloying with palladium (Pd) and yttrium (Y) elements increases surface pH by accelerating cathodic reaction and forms Y-containing precipitates as heterogeneous nuclei, respectively, promoting formation of protective corrosion product films and hence suppressing corrosion significantly under static immersion and erosion-corrosion conditions. Moreover, the heterogeneous nucleation strategy is confirmed to have long-term (90 d) effectiveness and is successfully used to develop commercial 90/10 copper-nickel alloys with superior corrosion resistance.
