DOUBLE LAYER SLIDE MEMBER

摘要

PROBLEM TO BE SOLVED: To improve corrosion resistance of a metal porous member constituting a porous layer in a double layer slide member having a back metal layer and a porous layer formed on a surface of the back metal layer.SOLUTION: The double layer slide member includes a back metal layer mainly composed of a steel plate, a porous layer having a metal porous member, and a resin composition filled in the metal porous member. The metal porous member has a granular portion 23 and a constricted portion 25 and includes a structure in which the granular portions 23 are joined together by the constricted portion 25. A part or all of the constricted portion 25 has a Bi phase 26 and a Sn-Ni-Cu intermetallic compound phase 27.
