为了改善硝基胍发射药的燃烧性能，利用溶剂对其表面进行物理侵蚀处理，在硝基胍发射药表面层100μm深度范围内形成不同的微孔结构表面。采用扫描电镜观察4种发射药样品的表面微观形貌，通过密闭爆发器实验获得4种发射药燃烧的压力-时间曲线，分析了发射药的燃烧性能变化。研究结果表明，经表面物理侵蚀制备的1#发射药样品质量损失为1.94%时，形成的微孔结构有利于提高发射药的综合燃烧性能，表面微孔结构降低了硝基胍发射药的燃速压力指数。

In order to improve the combustion performance of nitroguanidine propellants,the physical solvent surface erosion is conducted,and the various micro-porous structures surface are formed in the 100 μm depth range of the nitroguanidine propellant surface layer. The surface micro-structure of four propellant samples are observed by scanning electron microscope,their combustion pressure-time curves are obtained by the closed bomb test,and the combustion performance changes of propellants are analyzed comparatively. The results show that,when the 1# propellant sample through physical solvent surface erosion losses 1. 94% mass,the formed microporous surface structures can improve the comprehensive combustion performance and reduce the burning-rate pressure exponent of ni-troguanidine propellants.
