摘要

The bell (1) has a body, which axially extends on the basis of supply to a bell edge, where the body has a surface structure at an edge area at an interior side. The surface structure is irregular and is formed by applied material or by recesses, where the material is silicon, sand, ceramic material and diamond. The recesses are formed by the structure or the material of the body. The body is formed as two-piece by a supply-sided base (15) and a circular bell edge part (13). The base is manufactured from aluminum, and the bell edge part is manufactured from titanium or a titanium alloy.
