“…As noted, only N bonded to Cr, i.e., CrN, shows a marked energy shift ͑"chemical shifts"͒. 19,20 On the increasing temperature, the N 1s core electron level shifts to lower binding energies, in agreement with the formation of CrN precipitates observed in the BEI micrograph ͓see Fig. 4͑b͔͒.…”

Process window and mechanism of surface property enhancement of 9Cr18 steel using plasma immersion ion implantation J. Vac. Sci. Technol. B 17, 851 (1999) In this work we report a study of the structural modifications and corrosion behavior of martensitic stainless steels ͑MSS͒ nitrided by plasma immersion ion implantation ͑PI 3 ͒. The samples were characterized by x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, photoemission electron spectroscopy, and potentiodynamic electrochemical measurements. Depending on the PI 3 treatment temperature, three different material property trends are observed. At lower implantation temperatures ͑e.g., 360°C͒, the material corrosion resistance is improved and a compact phase of -͑Fe, Cr͒ 3 N, without changes in the crystal morphology, is obtained. At intermediate temperatures ͑e.g., 430°C͒, CrN precipitates form principally at grain boundaries, leading to a degradation in the corrosion resistance compared to the original MSS material. At higher temperatures ͑e.g., 500°C͒, the relatively great mobility of the nitrogen and chromium in the matrix induced random precipitates of CrN, transforming the original martensitic phase into ␣-Fe ͑ferrite͒, and causing a further degradation in the corrosion resistance.

“…Since its birth, nitriding has been used principally for steels to improve their surface hardness and tribological properties. Most recently, the authors and co-workers have succeeded in the electrochemical surface nitriding of the SUS430 ferritic stainless steel (Fe-18 wt% Cr) [20]. Fig.…”

Novel electrochemical reactions in molten salts related to electrodeposition and electrochemical synthesis are reviewed to show their usefulness and possibilities in producing functional materials. Surface nitriding of various metals and stainless steels is possible by the use of anodic reaction of nitride ion (N3-) in LiCl-KCl-Li3N melts. Electrochemical hydrogen absorption/desorption reaction occurs in molten salts containing hydride ion (H-). Electrochemical implantation and displantation can be applied to form transition metal-rare earth metal alloys in LiCl-KCl melts containing rare earth chlorides. As non-conventional electrochemical reactions, direct electrochemical reduction of SiO2 to Si, discharge electrolysis to form metal oxide particles and electrochemical plantation of Zr on ceramics are described

“…These steels are to be welded in the form of slim segments to ensure no loss of grain development in microstructure which may end up with properties diminishment when thicker segments are employed. [13][14][15][16] 2 Experimental procedure As the temperature constantly increases, the specimens are allowed to develop a nitrided layer. Now, the experimentation timing is varied accordingly for all four samples by taking out sample from furnace after every 45minutes.…”

AISI 430 Ferritic Stainless Steel is well known for its good corrosion resistance applicable for high resistance to pitting and stresses. But it lacks in its wear resistance and hardness in order to improve the mechanical properties of AISI 430 Ferritic Stainless-Steel materials Nitriding Heat Treatment is chosen in this project. The samples are taken in the form of cylindrical shapes with diameter 10mm and length 40mm respectively. The specimen is subjected 4 numbers being the highest treated to saturated limit. One specimen is kept as untreated for comparison purpose. Wear test will be carried out under constant speed and with variable load by pin on disk wear testing apparatus. Finally, all the specimens are subjected to various metallographic tests like SEM (Scanning Electron Microscope) and EDAX (X-ray Despresive Analysis) or XRD (X-ray Diffraction) and the results are compared.
