Research Status and Prospect of Foam Aluminum Drainage Behavior

During the preparation of aluminum foam by liquid phase method, the molten aluminum alloy drainages under the action of gravity and capillary force, resulting in liquid film thinning until rupture, and then adversely affects the quality and performance of aluminum foam products. The current research status of the drainage behavior of aluminum foam was described from the research method of drainage behavior and the stabilization method of aluminum foam, which can provide references for relevant personnel.
