摘要
喉衬材料不仅与发动机安全性,也与发动机推力和可靠性等指标密切相关。随着发动机性能的不断提升,喉衬的服役工况愈加恶劣,而常用喉衬材料由于抗热震性不足、高温力学性能低、抗烧蚀弱等问题,已难以满足性能要求。本文系统归纳了国内外钨合金喉衬材料的研究进展,总结了现用钨合金前驱粉体的制备技术、烧结工艺以及成型技术的不足,结合研究团队在喉衬用钨合金材料的粉体制备工艺、成型技术等方面的进展与成果,提出了新型钨合金喉衬材料的发展趋势,从喉衬材料方面为新一代大推力固体发动机性能提升提供了坚实的技术支撑。
Throat lining materials are closely related not only to engine safety,but also to indicators such as thrust and reliability.With the continuous improvement of engine performance,the service conditions of throat lining are becoming more and more harsh,and the commonly used throat lining materials have been difficult to meet the performance requirements due to insufficient thermal shock resistance,low mechanical properties at high temperatures,and weak ablation resistance.In this paper,the research progress of tungsten alloy throat lining materials at home and abroad is systematically summarized,and the shortcomings of the preparation technology,sintering process,and molding technology of the existing tungsten alloy precursor powder are identified.Taking into account the progress and achievements of the project team in the powder preparation process and forming technology of tungsten alloy throat lining materials for throat lining.The development trend of new tungsten alloy throat lining materials is proposed.This may provide a solid technical support for the performance improvement of a new generation of high-thrust solid engines from the aspect of throat lining materials.
