摘要:
以Ni71CrSi为中间层在1180 ℃×30 min的钎焊条件下，对C/C复合材料和镍基高温合金进行钎焊试验。研究了Ni71CrSi对C/C复合材料和表面SiC改性的C/C复合材料的润湿性。利用扫描电子显微镜、能谱分析仪、万能试验机和微米压痕仪分别对接头的界面组织和断裂过程及接头的显微硬度分布进行了研究。结果表明，表面未改性的C/C复合材料在连接过程中直接失效，而表面SiC改性的C/C复合材料与镍基合金的接头连接良好，且接头剪切强度达到35.08MPa，断裂方式呈假塑性断裂。机理分析表明，镍基钎料较好地润湿表面SiC改性的C/C复合材料，接头的显微硬度分布呈中间高两边低的变化趋势，且形成了表面改性C/C/Ni(s.s)+Cr7C3+Ni3Si/Ni(s.s)+Cr3C2+Ni3Si/Ni(s.s)+Cr3C2+MC+Ni3Si/Ni3Si+ MC +Ni(s.s)/GH3044界面结构。
Abstract:
C/C composites and Nickle-based superalloy GH3044 were brazed at 1180 ℃ for 30 min using the Ni71CrSi filler as interlayer. The wettability of filler on the surface of C/C composites and SiC modified C/C composites was studied. The chemical element distribution, microstructure, shear strength and hardness distribution of the joint between C/C composites and GH3044 were investigated by scanning electron microscopy, energy-dispersive spectrometry, material universal testing machine and Micro-indentation instrument, respectively. Results showed that the joint without SiC coating got failed during the brazing process. Ni71CrSi can well braze Nickle-based superalloy and C/C composites with SiC coating. The shear strength of joint with SiC coating at room temperature was up to 35.08 MPa. The joint exhibited pseudo-plastic fracture behavior. Mechanism analysis indicated that this filler could wet modified C/C composites well. The hardness distribution of the joint presented a trend with high value at the middle and low value at the both sides, and the interface structure of joints was: C/C composites with SiC coating/Ni(s.s)+Cr7C3+Ni3Si/Ni(s.s)+Cr3C2+Ni3Si/Ni(s.s)+Cr3C2+MC+Ni3Si/Ni3Si+ MC +Ni(s.s)/GH3044。
