Abstract: Preparing and operating a vaporizer body in a PVD-metallization system for continuously supplying and vaporizing metal. A layer structure deposited onto the vaporizer body comprising sinterable powder material in a substantially unsintered state, to which the metal is supplied, is deposited as a raw layer structure onto the vaporizer body and sintered onto the same in the metallization cycle by heating the vaporizer body. The layer structure is consumable during the metallization process and can be replaced directly in the metallization system after each metallization cycle.
