本文分两个部分,前一部分扼要论叙了钨渗铜喉衬的工艺和工艺参数选择依据;后一部分侧重将钨渗铜喉衬制品与美国八十年代推出的冷等静压粉末冶金技术制造的钨渗铜燃气舵从原料、工艺途径、中间性能、制品质量控制和检验等几个方面进行了全面分析比较。尽管两种制品使用条件和状态有所不同,但从制品的工艺和质量来看,钨渗铜喉衬已达到国外同类型材料的水平。
This article is divided into two parts, the first part of a brief discussion of the process of tungsten infiltration copper throat lining and process parameters to choose based on the latter part of the focus on the tungsten infiltration copper throat lining products and the United States launched the cold isostatic pressing powder metallurgy technology Tungsten infiltration copper gas helm from the raw materials, process, intermediate performance, product quality control and inspection, and several other aspects of a comprehensive analysis and comparison. Although the two products use different conditions and conditions, but from the product of the process and quality point of view, tungsten copper lining has reached the level of the same type of material abroad.
