Exploitable results Surface preparation on tools prior to physical vapour deposition Several machining processes namely grinding, tungsten electrodischarge machining (W-EDM), sink-EDM and electrochemical machining (ECM) were used to machine surfaces of tool materials (tool steels, carbides and cermets). The influence of machining conditions on the properties of a physical vapour deposition (PVD) titanium nitride coating has been studied. First results are available and can be transferred to industrial practice subsequent to the project. 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.
