中文摘要:
      本研究采用原位反应法对不同钨含量的钼钨合金表面进行渗氮-渗硅处理,制备得到高温抗氧化涂层。采用扫描电子显微镜及X射线衍射分析了钼钨合金中钨含量对涂层形貌和结构的影响,并评价了涂层在1600℃的抗氧化性能,简要分析了涂层的抗氧化机理。研究表明,随着钼钨合金中钨含量的增加,涂层表面硅渗出量减少,说明钨含量的增加可以有效地减缓Si元素的向外扩散;1600℃的高温氧化实验证实了Mo-30%W表面涂层的抗氧化性能最为优异,抗氧化时间长达327 h。实验表明,钨含量的增加在一定程度上提升了涂层的抗氧化性能。
Preparation and Properties of Anti-oxidation Coatings of Molybdenum-Tungsten Alloy
英文关键词:Mo-W alloy  W content  high temperature  anti-oxidant coating
英文摘要:
      High temperature oxidation resistant coatings were prepared by nitriding and siliconizing the surface of Mo-W alloys with different tungsten content by in-situ reaction method. The influence of W content on the morphology and microstructure of coating was analyzed by Scanning Electron Microscope and X ray diffraction. The oxidation resistance properties were also evaluated. In addition, the mechanism of anti-oxidant was researched. The results indicate that the amount of silicon seepage on the coating surface decreases as W content in Mo-W alloy increasing, which reveals that the increase of W content can slow down the outward diffusion of Si element effectively. Furthermore, the high temperature oxidation experiment at 1600℃ proves that the Mo-30%W surface coating has the best oxidation resistance, and the oxidation resistance time is up to 327 h. As a result, the increase of tungsten content improves the oxidation resistance of the coating to a certain extent.
