In this study the effects on resistance to corrosion of a low alloy steel after plasma nitriding has been reported. Nitriding was performed at temperature 450 °C and also 520 for same duration 10 h in nitrogen hydrogen (80:20) gas mixture. Sample holder biased −250 V working pressure kept around 500 Pa. After samples along with bare were exposed X-ray diffraction (XRD) understand phase formatio...

Nitriding of Fe-1 wt.% Cu and Fe-5 alloys at 813 K leads to the formation predominantly γ′-iron nitride phase (γ′-Fe4N) when using nitriding conditions, which lead pronounced ε-iron (ε-Fe3N1+x) upon pure α-Fe. Energy dispersive X-ray analysis reveals that developing γ′ can attain a content corresponding base material. In contrast, tiny amounts ε-nitride eventually develop contain considerably l...

Self-lubricating coatings can be used to increase the service life of machine parts which are subjected high mechanical loads. The present work is concerned with combination nitriding and a subsequent Ti-doped MoS2 coating. focus investigations on impact compound layer wear behavior coating since changes in surface topography due growth pore formation inside layers expected have an adhesion str...

Abstract A typical nitrogen expanded austenite layer is formed by plasma-based low-energy ion implantation (PBLEII) on AISI 304L austenitic stainless steel at a moderate temperature of 380 °C. The dislocation self-organization structure in the characterized as an evolution from partial and Lomer-Cottrell dislocations inner near interface to multilayer stacking faults outer nitrided layer. self-...

A special additive manufacturing (AM), called as Direct Metal Laser Sintering (DMLS), is a technology that produces 3D workpieces using wide range of different metals raw materials. The aim current research to investigate the plasma nitriding effect on DMLS produced samples. direct treatment was achieved at 440 °C for 4 hours with 75%N2 – 25%H2 gas mixture. Before treatment, 316L austenitic sta...
