The present disclosure generally relates to a sealed metal laminate structure comprising: a metal layer having a first surface and an opposite second surface; a first enamel layer laminated on the first surface of the metal layer, except at an exposed metal protrusion at a perimeter edge of the sealed metal laminate structure; a second enamel layer laminated on the second surface of the metal layer, except at the exposed metal protrusion at the perimeter edge of the sealed laminate structure; and a phosphate sealer deposited on the exposed metal protrusion of the sealed metal laminate structure. The present disclosure also relates to a metal laminate structure without a phosphate sealer. In addition, systems and methods for treating workpieces, including metal laminate structures, are discussed.

Metal laminate structures with systems and methods for treating

Various embodiments include a sealed laminated metal structure. This laminated metal structure has a metal layer, where the metal layer has a first surface and an opposite second surface. A material is laminated on each of the first and second surfaces of the metal layer. In some cases, the laminated metal structure is removed from a larger laminated sheet of metal. The laminated metal structure is subjected to alternating current electrolytic deburring and cleaning to remove any burrs along the perimeter edge. After deburring and cleaning, a sealer, which is a phosphate compound, is deposited on the perimeter edge of the laminated metal structure where the metal is exposed using alternating current.

Systems and methods for controlled and precise EDM manufacturing of a component are disclosed. In one embodiment, a system includes: a tank for holding a fluid; a first electrode array in the tank, the first electrode array including a plurality of electrodes configured to shape a workpiece; a workpiece fixture for positioning the workpiece at least partially immersed in the fluid and proximate the first electrode array; a pulse generator for creating an electric discharge between the workpiece and the first electrode array to remove material from the workpiece; a gap sensing circuit communicatively connected to the workpiece and the first electrode array, the gap sensing circuit configured to monitor the electric discharge between the workpiece and the first electrode array; and a computing device communicatively connected to the gap sensing circuit and the workpiece fixture, the computing device manipulating a position of the workpiece in the tank relative the first electrode array based upon data obtained from the gap sensing circuit.

Electric discharge machining die sinking device and related method of operation

Methods of forming a blade and rendering a blade resistant to erosion includes positioning a backing plate(s) or elongated backing plate(s) adjacent at least one side of a forward face of a leading edge surface of the blade. The methods include depositing an erosion resistant material in a plurality of layers by fusion bonding the erosion resistant material to the forward face of the leading edge surface of the blade. The backing plates providing a template or guide for depositing the plurality of layers of erosion resistant material. The plurality of layers of erosion resistant material form an erosion shield and a leading edge of the blade. Methods include removing the backing plate.

Methods of forming blades and method for rendering a blade resistant to erosion

A system includes an electrolytic deburring tool, which includes a first electrode configured to be positioned at a first gap away from a first edge of a workpiece, a second electrode configured to be positioned at a second gap away from a second edge of the workpiece, a first electrolyte supply configured to flow a first electrolyte through the first gap between the first electrode and the first edge of the workpiece, a second electrolyte supply configured to flow a second electrolyte through the second gap between the second electrode and the second edge of the workpiece, and a power supply configured to flow an alternating current through the first gap and the second gap to cause electrolytic dissolution through the workpiece from both the first edge and the second edge.
