Description

Technical field

[0001] The invention belongs to the technical field of metallurgy, and in particular relates to a novel porous metal composite material.

Background technique

[0002] As the concept of "energy saving and environmental protection" has attracted more and more attention from the society, lightweight has also been gradually applied to the field of ordinary cars, which can have excellent fuel-saving performance while improving handling. According to existing literature and patent reports, the way to reduce the weight of automobiles is to use a large number of lightweight porous materials on the body, such as alloy porous materials such as aluminum and magnesium, and polyurethane sandwich panel materials. The manufacturing costs of these materials are relatively high. Alloy porous materials such as aluminum and magnesium can only be foamed by thermal melting of the bulk metal, unlike metals such as porous iron and nickel, which can be prepared by electrodeposit...
