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.
Claims7
A method for use in forming a one-side oxidized silver-cadmium object comprising
- welding a non-silver-cadmium shield to one side of the silver-cadmium object with a weld having a width, the shield enabling the one side to resist oxidation,
- oxidizing the object under conditions that leave substantially unoxidized a layer of the object adjacent the one side, the oxidized object having an oxidized layer, the oxidized layer having a thickness, the width of the weld being greater than the thickness of the oxidized layer.
