为了制造效率更高,输出功率更大,同时散热更少的飞机引擎,需要燃料的燃烧温度也越来越高,因此航空发动机的生产商和涡轮发动机的制造者对材料和部件提出了新的要求。在较高的温度时,为了维持材料的机械性能和提高合金部件的控制能力,需要继续改进原有的高温合金或者开发新一代高温合金,同时制造者也在建立更加严格的规格界限和质量控制规程。本文主要描述具有高流速离子源的辉光放电质谱仪,这种仪器的分析速度快,灵敏度高,非常适合于高温合金的分析。仪器除了可以做搜索分析和基材的杂质元素含量的检测之外,其直接进样的方法可以更好地检测出各种元素在产品高温受热之后的分布情况,以及痕量元素在保护层和界面的纵向分布。
In order to make aircraft engines that are more efficient, have greater output power, and at the same time dissipate less heat, the combustion temperature of the fuel needs to be higher and higher, so manufacturers of aero engines and turbine engine manufacturers have proposed new materials and components Claim. At higher temperatures, in order to maintain the mechanical properties of the material and improve the control of alloy components, the need to continue to improve the existing high-temperature alloys or the development of a new generation of high-temperature alloys, while manufacturers are also establishing a more stringent specification limits and quality control Procedures. This article describes a glow discharge mass spectrometer with a high-flow ion source that is fast, sensitive and ideal for the analysis of superalloys. In addition to the search and analysis of impurities in the substrate material content of the instrument, the direct injection method can better detect the distribution of various elements in the product after high temperature heating, as well as trace elements in the protective layer and Vertical distribution of the interface.
