| 20110284385 | Method and Apparatus For Anodizing Objects - A method and apparatus for electrolytically treating a surface of a component includes a reaction chamber, a transport chamber and a fluid return path. The reaction chamber is adapted for placing at least a portion of the component therein, and holds a reaction fluid. Fluid enters the reaction chamber through a plurality of inlets. Each inlet directs the fluid toward the component at one or more non-zero vertical angles, and at one or more non-zero horizontal angles. The reaction chamber is a fixture having a cover with an underside shaped to direct the fluid to the surface of the component, such as by having a plurality of slopes. The inlets are through a material that is electrically non-conductive, such as ceramic, plastic, PVC, and fiber reinforced plastic, and/or the fixture further includes a titanium cathode ring that can be vertically adjacent the non-conductive material. | 11-24-2011 |
| 20090159450 | Method And Apparatus For Anodizing Objects - A method and apparatus of anodizing a component, preferably aluminum, is disclosed. The component is placed in an electrolyte solution. A number of pulses are applied to the solution and component. Each pulse is formed by a pattern including having three magnitudes. The third magnitude is less, preferably substantially less, than the first and second magnitudes, and all three magnitudes are of the same polarity. The pulse pattern may include alternations between the first and second magnitudes, and following the alternations, the third magnitude. Other patterns may be provided. The solution is in a reaction chamber, along with at least a portion of the component. The fluid enters the reaction chamber from a transport chamber through a plurality of inlets directed toward the component, preferably at an angle of between 60 and 70 degrees. The inlet is preferably the cathode, and the component is the anode, whereby current flows between the cathode and the anode in another embodiment. The inlets are in a side wall such that the fluid enters the reaction chamber substantially horizontally. The reaction chamber has at least one outlet beneath the inlets. The outlet may be in a bottom wall. The fluid follows a return path, such that the fluid returns from the reaction chamber to the transport chamber. The component is held in a mounted position mechanically or pneumatically in various alternatives. | 06-25-2009 |
