Erösen ötvözött duplex korrózióálló acélok bemutatása és azok forgácsolási körülményei
Az erĹ‘sen ötvözött korrĂłzióállĂł duplex acĂ©lok felhasználási terĂĽletei egyre nagyobb teret kapnak azok kĂĽlönleges tulajdonságainak köszönhetĹ‘en. A duplex acĂ©lok megmunkálhatĂłsága általában rossz. KĂsĂ©rleteink során TiAlN Ă©s TiALSiN tĂpusĂş PVD bevonattal ellátott forgácsolĂł szerszámmal rövidĂtett, száraz forgácsolási kĂsĂ©rleteket vĂ©geztĂĽnk, a G X2CrNiMoCuN 26-6-3-3 öntött acĂ©l forgácsolási problĂ©máinak feltárására. ErĹ‘s sorjakĂ©pzĹ‘dĂ©st Ă©s Ă©lrátĂ©t kĂ©pzĹ‘dĂ©st tapasztaltunk a forgácsolási kĂsĂ©rletek alatt, mely a szerszámĂ©lĂ©t károsĂtja. A rövidĂtett vizsgálatok alapján számottevĹ‘ kĂĽlönbsĂ©get nem tapasztaltunk a bevonatok hatása között
Difficulties in the Machining Super Duplex Stainless Steels
Super duplex stainless steels are used in increasingly more areas. The machinability of duplex stainless steels is generally poor. We performed dry turning tests on G X2CrNiMoCuN 26-6-3-3 casted superduplex steel, using two different PVD coated cutting inserts. One of them was coated with TiAlN and other with TiAlSiN. Strong burr and built-up edge formation were observed during our machining experiments; these damaged the edges of the tools. The shortened tests did not show significant difference betwen the effect of the coatings
