摘要 采用冷喷涂法制备了三元含能结构材料（ESM）Ni-Al-CuO，并研究了其在准静态和动态压缩条件下的力学性能。热爆炸和自蔓延燃烧模式下的能量释放特性包括点火温度、能量释放和燃烧波速。结果表明，Ni-Al-CuO 的屈服应力比 Ni-Al 高 50 MPa。发现初始反应温度为 450 °C，远低于 Al 和 CuO 之间的反应温度，对应于 Ni 和 Al 的反应。此外，Ni-Al-CuO ESM (859.2 J/g) 释放的能量比 Ni-Al (735.4 J/g) 释放的能量更多。 Ni-Al-CuO 涂层的燃烧波速约为 90 mm/s。 Ni-Al-CuO 的自蔓延燃烧是通过多级反应进行的，在此过程中，Al-CuO 反应是由 Ni-Al 反应引发的。图形摘要
AbstractTernary energetic structural material (ESM) Ni–Al–CuO was prepared by cold spraying, and its mechanical properties studied under quasi-static-state and dynamic compression conditions. Energy release characteristics including the ignition temperature, energy release, and combustion wave velocity were characterized in both the thermal explosion and self-propagating combustion modes. The results reveal that the yield stress of Ni–Al–CuO is 50 MPa higher than that of Ni–Al. The initial reaction temperature was found to be 450 °C, much lower than the temperature of the reaction between Al and CuO and corresponding to the reaction of Ni and Al. In addition, more energy was released by Ni–Al–CuO ESM (859.2 J/g) than by Ni–Al (735.4 J/g). The combustion wave velocity of the Ni–Al–CuO coating was about 90 mm/s. Self-propagating combustion of Ni–Al–CuO proceeded via a multistage reaction, during which the Al–CuO reaction was triggered by the Ni–Al reaction.Graphic Abstract
