PROCESS FOR PRODUCING A JOIN TO SINGLE-CRYSTAL OR DIRECTIONALLY SOLIDIFIED MATERIAL

摘要

In a process for producing a join between a first component (10) and a second component (20), wherein the second component (20) contains a single-crystal or directionally solidified material, the first component (10) and the second component (20) are provided. A polycrystalline layer (24) is produced on a joining surface (22) of the second component (20) provided for joining the second component (20) to the first component (10). The joining surface (22) of the second component (20) is joined to the first component (10) by friction welding.
