“…In vitro cell culture and cell proliferation (MTT) tests were performed on these specimens compared to SS 316L. Average % proliferation of MG-63 cells increased from ≈88 % for Un-USP to 98 % (USP samples 3-2) and 105 % (USP samples 2-2) in vivo rabbits without allergic reactions [47]. High corrosion resistance in the Fe-13.8Cr-8.9Mn alloy will be beneficial in the long term because toxic bone tissue can be minimized.…”

Traumatic, osteoarthritic, tumoral, and congenital bone issues impact human lives and health. The next generation of bone implants is made from biodegradable materials, including Fe-based materials with superior mechanical properties and high biocompatibility. However, efforts to inhibit the risk of inflammation and bacterial infection due to the biological response and corrosion properties of metals are a significant challenge. This study aims to develop biomaterials based on Fe-Cr-Mn alloys to obtain superior physical and mechanical properties through plasma nitriding. Each sample was plasma-nitridated in a vacuum chamber at various temperatures of 250–450 °C for 3 hours at a pressure of 1.8 kPa. Several main tests were performed to investigate the effects of plasma nitriding, such as the chemical compositions of raw material, surface nitrogen contents, phase changes, thickness, hardness, and corrosion. Those parameters were then used to evaluate plasma nitriding's effectiveness, including observing the change in phenomena at each temperature treatment. The results indicated that forming the S phase on the surface of Fe-13.8Cr-8.9Mn alloy is a saturated solution of nitrogen in ɣ-Fe, where the nitrogen content on the surface increases with increasing nitriding temperature. The layer's surface hardness is uniform across its whole thickness, which reduces as the grade of raw material passes through the nitride layer. The highest hardness at a nitriding temperature of 450 °C reached 625.3 VHN. The findings showed that the corrosion rate decreased significantly, reaching the lowest value, 0.0018 mm/year, at a plasma nitriding temperature of 450 °C. Plasma nitriding could enhance the physical and mechanical properties of Fe-Cr-Mn alloy

“…Steel and stainless steel have attracted much attention from many researchers owing to their machinability, high mechanical properties, heat resistance, corrosion resistance, etc., which allow them to be used in building development, automobiles, maritime, petrochemicals, medical apparatuses, and instruments. [1][2][3][4][5][6] However, it is well known that steel and stainless steel have poor fatigue strength and relatively low hardness performance, which limits their popularization and application, especially in the related field of high wear resistance and high strength. [7][8][9][10] For instance, high-strength steels are prone to surface defects that reduce the service life of the parts.…”

Surface severe plastic deformation is an important technology for the preparation of bulk ultrafine grain or even nanocrystalline materials. Based on the technical achievements made in the field of surface severe plastic deformation at home and abroad, this article presents the basic principles of various kinds of surface severe plastic deformation techniques in detail. In addition, the effects of surface severe plastic deformation on the microstructure and mechanical properties of steel and stainless steel are reported. The current status of research on the effects of surface severe plastic deformation on fatigue properties and the tribological and biological properties of steel and stainless steel are summarized. The problems of the current surface severe plastic deformation technology for steel and stainless steel are pointed out, and the future development trend is foreseen.

“…Iron-based biodegradable materials are promising candidates for orthopedic implants intended for load bearing bones [ 1 , 2 ]. The prospects for the use of these materials are due to their high strength: from 400 MPa, for pure iron [ 3 , 4 ] and up to 1550 MPa, for an iron-based alloy Fe-10Mn-1Pd [ 5 ].…”
