Abstract
The A122Si/ZL102 bimetal was designed and prepared by extrusion at near-eutectic temperature. The properties and fracture behaviors of different surface treatments between oxide film and zinc coating were compared between the A122Si and ZL102 bimetal. The average bonding strength of bimetal with intermittent oxide film interface was about 89. 3 MPa, which is higher than that of the bimetal fabricated by zinc coating method (about 76.3 MPa). During the process of extrusion, the oxidation film was extruded to crush and the metal was extruded through the micro-cracks of the oxidation film, then the two surfaces were joined together. Altogether, the results showed that extrusion at near-eutectic temperature is favorable for achieving a high-quality metallurgical bonded interface.
