摘要
The method of liquid solid roll bonding to produce bush material was described and used for producing a new bush material AlSn 8Si 2 5 Pb 2Cu 0 8 Cr 0 2 . The results show that the aluminum alloy solidifies so fast during the process of liquid solid roll bonding that the microstructure of alloy is made up of fine dendrite. The distributions of tin, silicon, lead, copper and chromium are uniform and dispersive, and the diffusion layer between aluminum alloy and steel is jagged. The stripped surface of steel is accompanied with matrix aluminum alloy, and the bonding strength of the interface between steel and aluminum alloy is near the strength of the matrix aluminum alloy.
