摘要:
为降低纯铝粉燃料的点火温度,提升体积燃烧热,改善热氧化特性,采用真空感应熔炼法制备了铝钆合金Al-10Gd和Al-2Gd,并破碎成粉制得样品。SEM、EDS图像显示:样品呈片状,元素分布均匀。结合微机全自动量热仪与真密度测试仪对样品的燃烧热进行测量与计算。结果表明:铝钆合金的质量燃烧热与纯铝粉相当,体积燃烧热要高于纯铝粉,在装药体积有限的情况下可以释放更多的能量。采用同步热分析仪研究了样品的热氧化特性。结果表明:铝钆合金的熔点和初始氧化温度均低于纯铝粉,反应放热至少持续到1 550.0 ℃以上,增重约60.42%。金属钆会促进铝粉的热氧化,从而降低燃料的着火点,使燃料迅速升温放热。
Abstract:
In order to reduce the ignition temperature of pure Al powder fuel, increase the volumetric combustion heat and improve the thermal oxidation characteristics, Al-10Gd alloy and Al-2Gd alloy were prepared by vacuum induction melting method. They were and broken into powder to prepare samples. SEM/EDS images show that the sample is flake and the element are evenly distributed. Combustion heat of sample was measured and calculated by computer automatic calorimeter and true density tester. Results show that mass combustion heat of Al-Gd alloy is equal to that of Al powder, but volume combustion heat is higher, so that more energy can be released in the case of limited fuel space. Thermal oxidation characteristics of the samples were studied by synchronous thermal analyzer. Results show that the melting point and initial oxidation temperature of Al-Gd alloy are lower than those of Al powder, the reaction exothermic lasts above 1 550.0 ℃, and the weight gain is about 60.42%. Gd can promote the thermal oxidation of Al powder, so as to reduce the ignition point of the fuel, and heat up the fuel rapidly to release heat.
