By treating surface of solid aluminum alloy with zincate treatment

the oxide film is removed accompanying with zinc layer deposition on aluminum

which can improve effectively the wettability between magnesium and aluminum.A satisfied metallurgical bonding cladding materials can be prepared on the basis of optimizing the liquid-solid bonding process of magnesium-aluminum.The microstructure and property investigation of interface reveal that it is key factors by removing the oxide layer and prevent its regeneration to improve the wettability of magnesium-aluminum bimetal.And celement diffusion occurred in the interface

and a metallurgical bonding was formed.
