    摘要: An electrode for an apparatus (1) for electrolytically treating a workpiece (3), the apparatus (1) being of a type arranged to convey the workpiece (3) with a surface to be treated past and directed towards a surface of the electrode, is divided into segments (23a-e) at at least this surface of the electrode. The segments (23a-e) are arranged next to each other in a first direction (x). Adjacent segments (23a-e) are separated from each other along respective segment edges (24a-f) such as to allow adjacent segments (23a-e) to be maintained at different respective voltages. The segment edges (24a-f) extend at least partly in a second direction (y) from a common value (y0) of a co-ordinate in the second direction (y) to an edge (25,26) of at least an electrically conducting part of the electrode surface, the second direction (y) being transverse to the first direction (x) and corresponding to a direction of movement of the workpiece, in use. The segment edges (24a-f) between at least one pair of adjacent segments (23a-e) extend along respective paths of which an angle to the electrode surface edge (25,26) decreases from the common value (y0) of the co-ordinate to the electrode surface edge (25,26).

    摘要: Methods of forming a cutting element include immersing at least a portion of a volume of polycrystalline diamond in a liquid electrolytic solution, applying a voltage between the polycrystalline diamond and a cathode in contact with the liquid electrolytic solution, and removing at least a portion of metal catalyst from interstitial spaces between adjacent diamond grains. The polycrystalline diamond includes interbonded diamond grains and metal catalyst particles in the interstitial spaces between adjacent grains of polycrystalline diamond material. Some methods include forming a barrier over a portion of a volume of polycrystalline diamond and transferring at least a portion of the metal catalyst from a portion of the polycrystalline diamond not covered by the barrier to a liquid electrolyte. Some methods include encapsulating a volume of polycrystalline diamond in a barrier and selectively removing a portion of the barrier from a first portion of the volume of polycrystalline diamond.

    摘要: In exemplary implementations of this invention, electrical connections are fabricated between two orthogonal surfaces by electroplating. The two surfaces are separated (except for the electrical connections) by a gap of not more than 100 micrometers. Multiple electrical connections may be fabricated across the gap. In preparatory steps, conductive pads on the two surfaces may be separately electroplated to build up “bumps” that make it easier to bridge the remainder of the gap in a final plating step. Alternately, electroless deposition may be used instead of electroplating. In exemplary implementations, a 3D probe array may be assembled by inserting array structures into an orthogonal base plate. The array structures may be aligned and held in place, relative to the base plate, by mechanical means, including side hooks, stabilizers, bottom hooks, alignment parts and a back plate.
