摘要

C/C composites can be jointed to super-alloy GH3044 with Ni/Ti interlayer by partial transient liquid-phase (PTLP) bonding under vacuum. Microstructures and element distribution were characterized by SEM and EDS. Interfacial structure of Ni/GH3044 diffusion layer + residual Ni layer + Ni-Ti intermetalics + reaction layer was formed under experimental conditions. With the increase of holding time, Ni ₃Ti intermetalic layer between NiTi and Ni gradually grew, while NiTi and Ni were consumed. However, large-size cracks were observed near the C/C composite/interlyer interface, resulting in unsatisfactory performance of obtained joints, with the shear strength of only 9.78 MPa.
