Özet

© 2016, © 2016 Informa UK Limited, trading as Taylor & Francis Group. In this work, the effects of pulsed plasma nitriding on HVOF-sprayed martensitic stainless steel coating were investigated. Martensitic stainless steel coating was pulsed plasma nitrided at 793 K under 0.00025 MPa pressure for 43200 s in a gas mixture of 75% N 2 and 25% H 2 . The pulsed plasma nitriding resulted in not only an increase in the surface hardness, but also improvement of dry sliding wear and tribocorrosion resistance of the HVOF sprayed martensitic stainless steel coating because of the Cr, Fe 3 , and Fe 4 N phases. However, the corrosion resistance of the HVOF-sprayed martensitic stainless steel decreased notably by nitriding process.
