A COMPARISON BETWEEN CVD AND PVD COATED CEMENTED CARBIDE CUTTING TOOLS

R. Porat , Y. Cassuto

Because cutting tools must withstand the stress conditions of machining, we are investigating cutting tools which not only will be wear resistant, but which will also retain their mechanical properties -- the ability to withstand interrupted cuts, thermal shock and a cyciing load as well as wear resistance. In this work we compare the results of grooving and milling tests made on hardmetals ISO K25 and ISO K35 coated by C.V.D. and P.V.D. coating processes. The CVD coatings were of TiCN or a combination of TiN and TiC. For comparison the same substrates were coated by two PVD processes with TiN or (TiNb)N.
