Abstract: Disclosed is a method of making a composite diamond having a cutting edge comprising a diamond compact bonded to a cemented carbide substrate, the diamond compact having a working surface, an edge of which provides the cutting edge, wherein the diamond compact comprises a first phase containing a polycrystalline mass of diamond particles and a second phase containing a diamond catalyst/solvent and ruthenium, which method includes the steps of providing a cemented carbide substrate, providing a layer of diamond particles on a surface of the substrate, providing a source of diamond catalyst/solvent and ruthenium, wherein the source of the diamond catalyst/solvent and ruthenium is the cemented carbide substrate.

Abstract: A method of fuze sterilization is provided for a fuze that includes a first component and a second component with a prescribed relationship being defined therebetween. The prescribed relationship is one that is required for proper detonation operation of the fuze. The first and second components are fabricated from materials having different galvanic potentials. An electrolyte is introduced between the first and second components to initiate galvanic corrosion of one of the components. The galvanic corrosion continues for a period of time until the prescribed relationship between the first and second components changes sufficiently to disable the detonation operation of the fuze.

Abstract: A detonation arrestor cuts the detonating cord of a dud line charge to prevent the pressure wave from a nearby explosion from sympathetically detonating the dud line charge. A housing of the detonation arrestor has a transverse passageway to receive the detonating cord of the dud line charge and an axial bore intersecting the passageway. A cutter piston having a cutter blade is disposed in the bore and is sized to permit axial displacement by a shallow dish-shaped diaphragm spring. The diaphragm spring has its center adjacent to one end of the cutter piston and laterally extends from the bore to be secured to the housing along its round periphery in a sealed relationship. The diaphragm spring is formed in the configuration of a Belleville spring from a spring material providing strength, rigidity, and spring modulus to snap to an extended position when displaced to a position past an over center position by an impinging pressure wave.
