| 摘 要： | The pressing bonding of steel plate to QTi3.5-3.5 graphite slurry was conducted. Under the conditions of 530 ℃ for the preheat temperature of dies, 45% for the solid fraction of QTi3.5- 3.5 graphite slurry, 50 MPa for the pressure and 2 min for the pressing time, the relationship between the preheat temperature of steel plate and interfacial mechanical property of bonding plate was studied. The results show that when the preheat temperature of steel plate is lower titan 618 ℃ , the interfacial shear strength of bonding plate increases with the increasing of the preheat temperature of steel plate. When the preheat temperature of steel plate is higher than 618 ℃ , the interfacial shear strength decreases with the increasing of the preheat temperature of steel plate. When the preheat temperature of steel plate is 618 ℃ , the highest interfacial shear strength of bonding plate of 127.8 MPa can be got.

| Abstract: | The pressing bonding of steel plate to QTi3.5-3.5 graphite slurry was conducted. Under the conditions of 530°C for the preheat
temperature of dies, 45% for the solid fraction of QTi3.5-3.5 graphite slurry, 50 MPa for the pressure and 2 min for the pressing
time, the relationship between the preheat temperature of steel plate and interfacial mechanical property of bonding plate
was studied. The results show that when the preheat temperature of steel plate is lower than 618°C, the interfacial shear
strength of bonding plate increases with the increasing of the preheat temperature of steel plate. When the preheat temperature
of steel plate is higher than 618°C, the interfacial shear strength decreases with the increasing of the preheat temperature
of steel plate. When the preheat temperature of steel plate is 618°C, the highest interfacial shear strength of bonding plate
of 127.8 MPa can be got.
