Galvanic cells may be created when dentures made of cobalt-chromium alloys are placed on teeth with metallic restorations. The power of such cells was evaluated in an in vitro galvanic using amalgams, gold alloy, and nickel-chromium alloys. The amalgams and one of the nickel-chromium alloys revealed high corrosion currents when placed in contact with cobalt-chromium alloy, the conventional amalgam showing the highest values. The gold alloy and another nickel-chromium alloy exhibited low corrosion currents and they were noble with respect to cobalt-chromium.
当由钴铬合金制成的假牙放置在有金属修复体的牙齿上时，可能会形成原电池。在体外原电池实验中，使用汞合金、金合金和镍铬合金对这种电池的电量进行了评估。当汞合金和其中一种镍铬合金与钴铬合金接触时，显示出高腐蚀电流，传统汞合金的腐蚀电流值最高。金合金和另一种镍铬合金的腐蚀电流较低，相对于钴铬合金而言它们是惰性的。
