| 摘 要： | 运用XPS分析手段表征了NEPE推进剂/衬层粘接界面的化学组成和老化历程,通过研究界面区的化学组成及分布,得出了界面区各位置及老化前后主要组分的变化;探讨了界面老化过程中元素结合能变化与老化失效的关系,认为界面区域中结合能是286～287 eV的羟基和结合能是401～402 eV的N活性基团的含量降低,以及硝基的分解是粘接界面失效的主要原因.

| Abstract: | The chemical composition and ageing course of NEPE propellant/line bondline was characterized by using XPS analysis. The change of main ingredients in different interface positions before and after ageing was obtained by studying interfacial chemical composition and distribution.The relation between interfacial elements bonding energy variations and ageing failure was discussed.The study shows that the main reason for interface failure is the decrease of active functional group content in interfacial areas,... |
