Cartridge for the generation of hydrogen for bonding materials

A method of bonding, said method comprising the steps of:

• providing a cartridge for the generation of hydrogen, that includes a case that defines an interior cavity, an igniter positioned within the cavity, an oxidizing agent positioned within the cavity;
• a structural component positioned within the cavity, the structural component being formed of a particulate embedded in a matrix and the particulate includes a metallic material, wherein the structural component is configured such that the metallic material and the oxidizing agent react together to generate hydrogen after the igniter generates sufficient heat to remove the matrix from the structural component and to initiate the reaction between the metallic material and the oxidizing agent;
• and a flyer wherein the cartridge is positioned relative to the flyer such that when the cartridge is discharged, the flyer is displaced into an anvil with sufficient force that the flyer is bonded to the anvil;
• discharging the cartridge;
• and
• bonding the flyer to the anvil.

A method for bonding, the method comprising the steps of:

• Providing a cartridge that includes a case that defines an interior cavity, an igniter that is configured to ignite when an electrical element embedded therein is exposed to an electrical voltage differential, an insert configured to define a plurality of chambers within the cavity and the insert includes aluminum particles that are embedded in a nitrocellulose matrix, an oxidizing agent including chemically bonded hydrogen and positioned within each chamber, and wherein the igniter is configured to initiate a reaction between the aluminum particles and the oxidizing agent that generates hydrogen, and a flyer;
• discharging the cartridge;
• propelling the flyer;
• contacting the flyer with an anvil with sufficient force that the flyer is bonded to the anvil to form a bonded part.
