  • Method for preventing oxidization of a silver-cadmium object
    Patent number: 5781993
    Abstract: A one-sided oxidized silver-cadmium object is formed. One side of a silver-cadmium object is covered with a non-silver-cadmium shield to enable the one side to resist oxidation. Then the object is oxidized under conditions that leave substantially unoxidized a layer of the object adjacent the one side. An oxidized silver-cadmium object has a non-silver-cadmium, oxidation-resistant shield attached to one side of the object, the object having a substantially unoxidized layer adjacent the one side.
