Use of physical vapour deposition coatings on several tool materials for different applications

In a systematic manner the influence of surface generation and surface preparation of several tool materials on the coated system performance was investigated.
Knowledge on the influence of grinding, polishing and spark erosion, and also on the influence of the cleaning procedure on the physical vapour deposition (PVD) coating (titanium nitride) adhesion was gathered. The results of this project fill in a part of the lack of data concerning these aspects. More research in this field is necessary. The technical and economical advantage of this know how will be that tool makers and tool users can deliver tools to the jobcoaters with an optimal surface state with respect to PVD coating.
