The present embodiments are directed to systems and methods for plating of work rolls. In one embodiment, a system includes an inner tank having an inner diameter dimensioned to receive a work roll, and an outer tank, wherein the inner tank is disposed coaxially within the outer tank. The inner tank and the outer tank may each include cylindrical shapes. A temperature regulating tank, positioned outside of the outer tank, may be in fluid communication with an annular space between the inner and outer tanks. An exhaust hood having a generally ring-shaped profile including a plurality of slots formed therein may suction fumes from the inner tank. An anode configuration also is disclosed, having a shunt incorporated into the anode, wherein current going to the anode passes through the shunt.

摘要:
A material surface treatment protocol (e.g., FIG. 13) uses concurrent electronic and photonic stimulation to generate an exothermic reaction and coat the surface (e.g., FIGS. 8 and 9) of a material, such as palladium. This protocol is performed at or near the boiling point of water within a sealed vessel that prevents the escape of steam and that is lined with silica or a similar glass to increase the silica available to the reaction. The great majority of the applied energy is heat used to elevate the temperature to near the boiling point, while concurrent stimulations provide only about 100 mW of additional energy for the surface treatment.
摘要:
A method of immersing an electrode in an electroplating solution while under vacuum, to substantially eliminate air and/or other gas from microscopic holes, cavities or indentations in the electrode. A method of electroplating an electrode in an electroplating solution including the application of a vacuum to the electrode while it is immersed in the electroplating solution to thereby substantially eliminate air and/or other gas from microscopic holes, cavities or indentations in the electrode. The electroplating liquid may be applied to only one side of the electrode (“the wet side”) in which case, sufficient time is allowed to pass for the immersion liquid to fill the microscopic through-holes, cavities or indentations in the electrode. An enhancement of this mode is to force liquid through the microscopic holes from the wet side. A highly penetrating solvent may be used as an immersion liquid. Alternatively, carbon dioxide can be used as an immersion liquid, in which case the liquid carbon dioxide may be obtained by adjusting the temperature and pressure conditions in a closed container of gaseous carbon dioxide.
摘要:
A plating method, employing a face-down manner of plating and using a resistor body between a substrate and an anode, can securely bring an entire surface to be plated of the substrate into contact with a plating solution without permitting intrusion of air bubbles to the surface to be plated. A resistor body is disposed above the anode and immersed in the plating solution, allowing the plating solution to flow along an upper surface of the resistor body from the periphery toward the center of the resistor body. Thus, a raised portion of the plating solution is created in the center of the upper surface of the resistor body. The substrate is then lowered with the surface facing downwardly so as to fill the space between the surface to be plated of the substrate and the upper surface of the resistor body with the plating solution.
