As a new type of functional and structural material,the porous metal materials have been widely used in the fields of sound absorption,energy absorption,fluid distribution,heat exchange,catalysis,filtration,and separation,which are the most widely used in the field of filtration and separation.Porous metal materials can achieve the liquid-solid and gas-solid filtration separation for the different fluids in the fields of petroleum and petrochemical,fine chemical,coal chemical,and other fields,and the requirements for the materials and mechanical properties of the porous metal materials used in the different fields are also different.The preparation process of porous metal materials used for filtration is relatively mature,but there is little investigation on the corrosion resistance and mechanical properties of the porous metal materials,which will directly affect the use effect and life of such materials.The research progress on the mechanical properties and corrosion resistance of the porous metal materials used for filtration in recent years was briefly reviewed in this paper,and the existing problems in the corrosion and mechanical behavior of such materials were discussed.Finally,the research direction of the porous metal materials used for filtration was prospected.
