Interconnection for two metallic joining partners for use in manufacturing of generators, has recesses formed in surface structure that are partially filled with adhesive, where surfaces of joining partners are expanded by surface structure

摘要

The interconnection has recesses (5,6) provided in a surface structure, where the connected surfaces (3,4) of the joining partners (1,2) are expanded by the surface structure. The recesses engage into one another in finished interconnection of the joining partners according to key-lock principle and are partially filled with a polymer-based adhesive (7) on the joining partner surface. The recesses are provided in the form of regular and irregular structures, ridges or grooves, pyramids, cones or cubes. The dimension of the recesses lies in the range of one micrometer to certain centimeters.
