摘要
铱具有高熔点和良好的化学惰性,是宇航工业领域1800℃以上难熔金属高温抗氧化涂层的首选材料。本文阐述了难熔金属表面制备铱涂层的迫切性和必要性,对铱的特点与性质进行了详细介绍,以及从美国、日本、欧洲和中国对铱涂层的制备方法和应用背景进行了综述,重点介绍了双辉等离子技术在难熔金属表面制备铱涂层的技术优势和组织结构。
Iridium is the most promising material due to its high melting point and good chemical inertness, which is one of the most potential high-temperature oxidation-resistant materials for refractory metals above 1800 oC in aerospace filed. In this paper, the impendence and necessity of the iridium coating on refractory metals were introduced. The properties of iridium were presented in detail. The deposition methods and applications of the iridium coating from American, Japan, Europe and China were reviewed. Further, the advantages of double glow plasma technology and microstructure of the iridium coating produced by double glow plasma on refractory metals were highlighted in this study.
