The bonding of steel plate with QTi3.5-3.5 graphite slurry was studied by using pressing bonding technique.The influence of pressing time on the interfacial mechanical property of bonding plate was researched. The results show that: under the conditions of 620℃ preheating temperature of steel plate, 530℃ preheating temperature of dies, 46% solid fraction of QTi3.5-3.5 graphite slurry and 50 MPa pressure, there exists a nonlinear relationship between pressing time and interfacial shear strength. The interfacial shear strength of bonding plate increases with increasing pressing time and reaches a largest value about 127 MPa when pressing time is longer than 120 s. At the interface with the best mechanical property, there exists a continuous Fe-Cu inter-diffusion zone and a metallurgical bonding.
