| 摘 要： | 采用固体粉末包埋渗硅工艺在铌表面制备了二硅化铌涂层,研究了渗硅过程中Si沉积的反应机理和二硅化铌涂层的结构.结果表明:涂层由单相的二硅化铌组成;Si的输运和沉积主要依靠硅的低氟化物SiF2完成.

| Abstract: | NbSi2 coating was formed on niobium by halide-activated pack cementation process. The microstructure of the as-formed coating and the possible reactions of Si deposition were investigated. The results indicate that the as-formed coating consists of single phase of NbSi2- SiF2 is responsible for the transportation and deposition of Si in the pack. |
