Plasma radical nitriding was performed to harden the surface of SKD 61 steel for 1-10 h at temperature range of 450-550 β’ C. The microstructures and material properties of the radical nitrided layer were characterized in order to investigate the effects of various radical nitriding processing parame

β¦ Synopsis
The crystalline structure profile of the compound layer obtained by pulsed plasma nitriding in steel gears is reported. The nitrogen depth profile obtained by Radio Frequency Glow Discharge Optical Emission Spectroscopy is correlated with both the nano-hardness and the crystalline Ξ΅-Fe 3 N /Ξ³β²-Fe 4 N phases identified in the nitrided layer by X-ray diffraction. These results show the importance to control the nitriding parameters to avoid abrupt hardness changes along the case that can jeopardize the gear performance.

Spark plasma sintering (SPS) is a new technique to rapidly produce metal matrix composites (MMCs), but there is little work on the production of TiB 2 -TiC reinforced steel matrix composites by SPS. In this work, in situ TiB 2 -TiC particulates reinforced steel matrix composites have been successful
