Compound material and its use

摘要

The composite component (10) has a first component (1), which has a surface structure (20) produced by an electromagnetic radiation, particularly a laser beam partially to a first contact surface (11). A form-locking connection has a contour between the two components, which is guided by a temperature increase or a temperature decrease due to different thermal expansion coefficients of the materials of the two components to an increased surface pressure between the two components. A second component (2) is provided with a second contact surface (12) cooperating with the first contact surface.
