摘要:

介绍一种高压燃气发射装置喷管喉衬材料的烧蚀试验方法.提供了用炮钢、钨渗铜、钨渗银、钽10钨、钼合金及铌合金等材料的喷管试验结果,其中以钽10钨的抗烧蚀性最佳.

Abstract:

Experimental method for ablation of throat liner material in a high pressure gas launch device is introduced.Experimental results of materials such as gun brass, tungsten infiltrated copper, tungsten infiltrated silver, tantalum 10-tungsten, and molybdenum alloy are presented in this paper. The tantalum 10-tungsten displayed the best ablation resistant ability.
