“…The role of USP on microstructural features and hardness was studied in detail, earlier [18]. It was observed that there is significant rise in the hardness with the duration of USP as well as with an increase in the shot diameter.…”

“…The phases present in stainless steel influence the cell adhesion and proliferation [41]. However, there is no phase change in the Fe-18Cr-22Mn-0.65N following USP [18]. USP causes grain refinement in the nanoscale regime without altering the chemistry in the surface region.…”

“…USP causes grain refinement in the nanoscale regime without altering the chemistry in the surface region. The corrosion resistance of this steel is enhanced following the USP [18] due to which the leaching out of elements during the long time implantation will be very low and chances of contamination in the implanted region will be reduced. Surface topography of material is influenced by the USP as shown in figure 5.…”

“…There are many surface modification techniques of implant materials that affect the surface properties [14][15][16][17]. Ultrasonic shot peening (USP) is one of them which was found to improve electrochemical corrosion and fatigue resistance of nickel-free grade steel significantly [18][19][20]. Nanostructured surface caused by USP has significantly large number of grain boundaries which provide high density of nucleation sites for oxide formation [21].…”

The rationale behind the success of nickel free or with extremely low nickel austenitic high manganese and nitrogen stabilized stainless steels is adverse influences of nickel ion on human body. Replacement of nickel by nitrogen and manganese provides a stable microstructure and facilitates better biocompatibility in respect of the conventional 316L austenitic stainless steel (316L SS). In this investigation, biocompatibility of the high-manganese and nitrogen stabilized (Fe–18Cr–22Mn–0.65N) austenitic stainless steel was studied and found highly promising. In vitro cell culture and cell proliferation (MTT) assays were performed on this stainless steel and assessed in respect of the 316L SS. Both the steels exhibited similar cell growth behavior. Furthermore, an enhancement was observed in cell proliferation on the Fe–18Cr–22Mn–0.65N SS after surface modification by ultrasonic shot peening (USP). The mean percent proliferation of the MG-63 cells increased from ≈88% for Un-USP to 98% and 105% for USP 3–2 and USP 2–2 samples, respectively for 5 d of incubation. Interestingly, in vivo animal study performed in rabbits for 3 and 6 weeks showed callus formation and sign of union without any allergic reaction.

Aluminium alloys are most suitable for light weight applications. This research paper investigates the fatigue strength of Aluminium alloy 2024-T3 after shot peeing process using nickel shots. Nickel shots are used in this research to investigate the influence of nickel on the fatigue strength of aluminum 2024-T3 alloy. Compressed air is used for shot peening process. Shot peening process parameter values are chosen based on response surface method (RSM) to conduct the experiments. Desirability approach is used to get the optimized values of process parameters. High cycle fatigue testing is performed to find the fatigue strength of specimens before and after shot peening process. An increase in the fatigue strength up to 34% is observed after peening using the nickel shots. FESEM and EDS tests revealed the presence of nickel on the surface of aluminium 2024-T3 specimen after shot penning with nickel shots.
