Kompositstrukturen und Verfahren zum Herstellen derselben

摘要

A composite structure is manufactured by joining a first material (2) preferably made of a magnetically permeable material having a first joining surface (11a) in which a recess (7) having an overhang surface (6) is formed, to a second material (3) preferably made of an electrically conductive material having a second joining surface (11b), to be joined to the first joining surface (11a) of the first material. On the second joining surface (11b), a protrusion (9) having an outer configuration substantially corresponding to the inner shape of the recess (7) is integrally formed. The first and second materials (2, 3) are firmly mechanically joined to each other by, for example, a casting method, a rolling method, a pressing method, or a method by utilizing a plastic flow of the second material (3).
