| 目的 在 Nb-Ti-Si 合金表面制备 MoSi2 涂层。 方法 先进行辉光离子渗 Mo,再进行包埋渗 Si。分析温度对渗 Mo 层表面形貌、厚度、元素互扩散的影响,以及渗 Si 后涂层的表面形貌和结构。 结果 在1100 ℃进行辉光离子渗 Mo,渗 Mo 层与基体形成了显著的互扩散。 对渗 Mo 层进行包埋渗 Si 后,所形成的涂层组织致密,具有多层结构,由外向内依次为 MoSi2 层、NbSi2 层和 Nb5Si3 层,在 MoSi2 和 NbSi2 层之间存在 (Mo,Nb)Si2 互扩散区。 结论 通过辉光离子渗/ 包埋渗的方法,可以在 Nb-Ti-Si 合金表面制备MoSi2 涂层,且涂层与基体呈冶金结合,结合较好。 |

| Objective To prepare the MoSi2 coating on the surface of Nb-Ti-Si alloy. Methods The coating was prepared through glow plasma deposition of Mo and pack siliconization. The effects of temperature on the microstructure, thickness and element distribution of the deposited Mo layer were analyzed, and the coating structure of the Mo layer after siliconization was investigated. Results Elements inter-diffusion between the glow plasma deposited Mo layer and the substrate was significant at 1100 ℃; after siliconization, dense MoSi2 coating was formed on the substrate. The MoSi2 coating had a multi-layer structure. From the surface to the substrate, the MoSi2 coating was consisted of the MoSi2 layer, the NbSi2 layer and the Nb5Si3 layer; a (Mo,Nb)Si2 inter-diffusion zone was formed between the MoSi2 layer and the NbSi2 layer. Conclusion The MoSi2 coating could be prepared on the surface of the Nb-Ti-Si alloy through glow plasma deposition of Mo/ pack siliconization. The coating had metallurgical bonding with the substrate. |
