Abstract: The pressing bonding of steel plate to QTi3.5-3.5graphite slurry was studied. The bonding conditions were 620 ℃ for preheating temperature of steel plate, 530 ℃ for preheating temperature of dies, 50 MPa for pressure and 2 min for pressing time. The relationship between the solid fraction of QTi3.5-3.5graphite slurry and the interfacial mechanical property of bonding plate was obtained. The results show that when the solid fraction of QTi3.5-3.5graphite slurry is smaller than 45.8%, the interfacial shear strength of bonding plate increases with the increasing of solid fraction. When the solid fraction is larger than 45.8%, the interfacial shear strength decreases with the increasing of solid fraction. When the solid fraction is 45.8%, the largest interfacial shear strength of bonding plate 127 MPa can be got, and the interface is made up of Fe-Cu solid solution.
