| 20150114846 | METHODS OF FORMING CUTTING ELEMENTS BY OXIDIZING METAL IN INTERSTITIAL SPACES IN POLYCRYSTALLINE MATERIAL - Methods of forming a cutting element include disposing a volume of polycrystalline material adjacent a liquid electrolytic solution and applying an electrical between the polycrystalline material and a cathode in contact with the liquid electrolytic solution to increase an oxidation state of the metal catalyst material. The polycrystalline material includes interbonded grains of hard material and metal catalyst particles in the interstitial spaces between adjacent grains of hard material.

| 20150329987 | Electrochemical Machining Method for Rotors or Stators for Moineau Pumps - An ECM method involves the use of a thin hollow electrode assembly that carries the electrolyte within and that is advanced relatively to the workpiece. The small profile of the electrode results in a minimal removal of metal in forming the desired rotor or stator shape. The electrode profile allows significant power consumption reduction or increased machining speed for a given rate of power input. The electrode can be a unitary ring shape or can be made of segments that are placed adjacent each other so that a continuous shape is cut. Not all the lobes of the stator or rotor have to be cut in the same pass. Electrode segments can be used to sequentially provide the desired lobe count in separate passes. The lobe shapes in the electrode can be slanted to get the desired rotor or stator pitch or they can be aligned with the workpiece axis. | 11-19-2015 |
| 20160130717 | Methods and Apparatuses for Delaminating Process Pieces - Methods and apparatuses for delaminating workpieces are provided. In one or more aspects, a method can include processing or otherwise delaminating the workpiece by separating a delamination stack and a support substrate disposed thereon. The workpiece that can include a sacrificial layer disposed between the delamination stack and the support substrate. The method can include exposing at least a portion of the workpiece to an electrolyte solution, applying an electrical current through the sacrificial layer and the electrolyte solution, selectively removing the electrically conductive or semiconductive material from the sacrificial layer during an etching process, and separating the delamination stack and the support substrate one from the other. The delamination stack can include a process piece that can be one or more wafers or devices (e.g., thin-film devices) or one or more portions of the one or more wafers or devices. | 05-12-2016 |

| 20100072077 | ELECTROLYTIC DEBURRING APPARATUS AND METHOD - Apparatuses and methods for toolless electrolytic deburring are disclosed in which a charged electrolyte stream flows through a hose and nozzle and can be selectively directed at a desired portion of an external or internal surface of a workpiece. The nozzle or the workpiece can be manipulated to vary the electrolytic deburring working gap so as to control the intensity of the electrolytic deburring and the portion of the workpiece that is electrolytically deburred. The electrolytic deburring is preferably performed in an enclosure having a glove which has an electrical contact that can be used to electrically connect the workpiece to the DC power supply anode simply by gripping the workpiece. | 03-25-2010 |
| 20100270168 | METHOD FOR REMOVING MATERIAL FROM A COMPONENT, AND ELECTRODE - A method for removing material from a component that is connected as an anode is disclosed. In an embodiment, an electrode that is connected as a cathode is guided to the component such that a gap is formed, an electrolyte is introduced into the gap, and a closed system is formed for the electrolyte by the formation of a duct. The electrolyte is continuously guided from an inlet opening to an outlet opening of the duct. Forming the duct, e.g., by guide elements that are mounted on the electrode, ensures that only those surface parts of the component to be machined from which material is to be removed enter in contact with the electrolyte while the other surface parts do not enter in contact with the electrolyte. Since the electrolyte is continuously guided across the surface, used electrolyte is continuously discharged along with residual matter while fresh electrolyte is delivered. | 10-28-2010 |

One method comprises forming one or more grooves in an outer surface of a substrate. Each groove has a base and extends at least partially along the outer surface. A sacrificial filler is deposited within the groove, a second filler is deposited over the sacrificial filler, and a coating is disposed over at least a portion of the outer surface and over the second filler. The method further includes removing the sacrificial filler and at least partially removing the second filler from the groove(s), to define one or more channels for cooling the component. | 10-11-2012 |
