Fuzzy interface layer for thermite and primer made from thermite with fuzzy layer

A primer, comprising

• a substrate having a deposition surface and a rear surface;
• alternating layers of metal oxide and reducing metal deposited upon the substrate, the alternating layers of metal oxide and reducing metal being structured to react with each other in response to an impact applied to the rear surface of the substrate;
• and
• a fuzzy interface layer disposed between each metal oxide layer and reducing metal layer, the fuzzy interface layer containing reducing metal, reducing metal oxide, and metal oxide, the reducing metal, reducing metal oxide, and metal oxide being at least partially mixed together.

A cartridge for a firearm, the cartridge comprising:

• a casing having a front end, a back end, and a hollow interior;
• a bullet secured within the front end of the casing;
• a propellant disposed within the hollow interior;
• a primer secured within the back end of the casing, the primer being in communication with the propellant, the primer comprising;
• a substrate having a deposition surface and a rear surface;
• alternating layers of metal oxide and reducing metal deposited upon the substrate, the alternating layers of metal oxide and reducing metal being structured to react with each other in response to an impact applied to the rear surface of the substrate;
• and
• a fuzzy interface layer disposed between each metal oxide layer and reducing metal layer, the fuzzy interface layer containing reducing metal, reducing metal oxide, and metal oxide, the reducing metal, reducing metal oxide, and metal oxide being at least partially mixed together.
