摘要： An copper alloy material having a structure in which fine particles with a mean particle size of 50 nm or less have precipitated in a structure composed of fibrous crystal grains with a minor axis length of 10 nullm or less which are composed of subgrains with a mean grain size of 3 nullm or less is obtained by extruding an alloy material represented by a general formula Cubal.Xa (wherein X is at least one element selected from the group consisting of Cr, Zr, Fe, P, and Ag; a is 1.5% by weight or less, and the balance is Cu comprising unavoidable impurities) at an extrusion ratio of 4 or higher and at a temperature of 300 to 600null C. The copper alloy material is preferably heat treated at a temperature of 350 to 700null C before and after the extrusion. The thus obtained alloy material is useful as an electrode material for welding because of improved mechanical properties, heat resistance, and high-temperature yield stress and exhibits a superior continuous welding ability (electrode life) as an electrode material.

摘要： A method for recycling thoriated tungsten objects such as thoriated tungsten scrap resulting from the fabrication of electrodes for lamps. The thoriated tungsten objects are oxidized, homogenized by mixing and chemically reduced under a hydrogen gas atmosphere to form thoriated tungsten. This method eliminates the need to separate the tungsten from its dopants. The thoriated tungsten obtained as the end product is returned to the production process and is preferably used as a raw material for the production of welding electrodes or thoriated tungsten discharge lamp electrodes.

摘要： An electrode for a plasma arc torch and method of fabricating the same are disclosed, wherein the electrode comprises a metallic holder defining a cavity in a forward end. An emissive element and separator assembly is positioned in the cavity. The emissive element has a layer of relatively non-emissive material on the outer surface thereof, which is preferably applied by heating the emissive element to a high temperature such that the emissive element becomes reactive, and spraying the relatively non-emissive material on the emissive element. The coated emissive element is positioned in the separator and the assembly is heated such that the relatively non-emissive material forms a strong bond between with the separator. The superior bonds between the emissive element and separator formed according to the present invention extend the life span of the electrode.

Thereby, the difficulties, that had been existed for quite a long time of its processing brittleness in forging the ceriated tungsten material over 1.0%, have now been satisfactorily overcome.* ceric oxide=ceria
