“…Researchers have found that by utilizing the transient high pressure formed during the energy release of energetic materials, atomic-level homogeneous assemblies can be generated at the interface of metal materials. This material preparation strategy has distinct high-efficiency characteristics, enabling the method to meet mass production requirements [10][11][12]. Because the material preparation process is primarily based on the explosion of energetic materials, this method of obtaining metal composite materials is also termed explosive welding or explosive cladding [13].…”

Industrial explosives with a low detonation velocity serve as the core-driven energy source for explosive cladding, but have a limited pressure output. A composite energetic system containing high-energy explosives/emulsion explosives can overcome this limitation. Accordingly, the search for high-energy explosives with intrinsic safety features is key to achieving such systems. Therefore, in this study, 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) with high-energy-insensitivity characteristics was selected as the energetic agent to prepare a composite energetic system with an ANPyO/emulsion explosive, and its safety and energy release effects were systematically studied. The experimental results showed that the content of ANPyO had a "linear" relationship with the apparent density of the developed composite energetic system, and had little effect on its impact and friction safety (the explosion probability was less than 10 %). In addition, the introduction of ANPyO did not have a significant impact on the detonation velocity of the composite energetic system, with an average detonation velocity of 2650 m • s À 1 . However, it did effectively improve the pressure output of the composite system. The peak pressure increased by 23.69 % from 27.27 kPa to 33.73 kPa, while the boosting rate increased by 88.09 % from 1256.68 kPa • s À 1 to 2363.70 kPa • s À 1 . The improvement in the pressure output endowed the ANPyO/emulsion explosive composite energetic system with excellent work capacity, enabling T2/Q235 to compound well during explosive cladding. The above studies prove that this system can effectively maintain the relationship between the safety and energy output, positively contributing toward the development of explosive cladding technology.
