Production of parts with at least one metallic foam layer

摘要

Preparation of semifinished product of component (9) having at least one foamed layer (1) formed with one or more type of propellant and one or more types of metal powder, and at least one thicker metal layer (2,3). The foamed layer is formed by pressure compacting a multi-component powder mixture and one or more metal layers (2,3) to give a semifinished product (4), which is heated, softened and compacted to a limited thickness. An independent claim is included for a device for production of the semifinished product as described above.
