摘要为准确地检测和评价含能材料的烧蚀性，以发射药为研究对象，在已有的发射药烧蚀性试验方法基础上，改进完善试验测量手段和评价方法；设计并制备了具有不同性质的发射药样品。通过半密闭爆发器烧蚀管法试验测定其烧蚀率，分别研究了爆热、爆温、燃气组分以及含能成分性质等因素对烧蚀性的影响，探讨了烧蚀机理。研究结果表明：
- 上一篇：年产两万吨流延薄膜的车间工艺设计
- 下一篇：水泥基聚合物防水涂料的自愈合研究
发射药爆温相近时，爆热对烧蚀性影响不明显，主要与发射药燃气对烧蚀管的烧蚀时间有关，烧蚀性与燃气冲刷烧蚀管期间的压力冲量接近指数增长关系；发射药爆热相近时，爆温对烧蚀性影响很大，两者接近指数增长关系。
发射药燃气组分中H2O对烧蚀系数影响较大，CO2影响较小，N2的影响与传统认识存在差异；适当减少燃气中O元素含量可能减小烧蚀性。燃气组分对烧蚀性影响关系复杂，与其它因素作用相互交叉，目前还难以单独定量描述。19790
超细粒度RDX对发射药的烧蚀性影响很小；大比容组份有利于降低发射药的烧蚀性，增加发射药中H元素含量，在爆温相近条件下提高火药力不会导致其烧蚀性增大。

Title Study on the energetic materials’erosion and erosion mechanism
Abstract
Detection and assessment the erosion of energetic materials accurately, we chose propellant as the research object, based on the existing experiment method of the erosion of propellants, improved the experiment measurements and evaluation methods; designed and prepared with different properties of propellant samples. The amounts of erosion were determined with semi-closed bomb experiment, researched for the influence of factors of explosion heat, explosion temperature, gases composition and energetic composition on the erosion, respectively, and explored the erosion mechanism. The experimental results showed that: when the explosion temperature of propellant is similar, the effect of explosion heat on the erosion is not obvious, it’s mainly related to the erosion time of propellant gas to the erosion tube, there is a closely index growth relation between the erosion and the pressure impulse of gas scouring the erosion tube; When the explosion heat of propellant is similar, the effect of explosion temperature on the erosion is very obvious, two of them are close to relation of index growth. The H2O of gases composition of these propellants had great impact on the erosion coefficient, and CO2 made ales impact on it, but there has some difference between traditional knowledge of the impact of N2; It’s possible to reduce the erosion by decreasing the content of oxygen of gases composition of these propellants. The relationship between these products and propellant erosion is complex, it is difficult to have a quantitative description separately. The RDX ultrafine particle size had less impact on the erosion of propellant; The big specific volume composition is benefit to reducing the propellant erosion and increasing the content of hydrogen, improve the force of gunpowder under similar conditions won’t cause the erosions increasing.
Keywords: Propellant; erosion; semi-closed bomb; erosion tube; Explosion heat；explosion temperature；Gas composition.
