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.
