“…The shot peening process was carried out under pressure of 0.4 MPa perpendicularly to the surface. According to previous publications [26,[28][29], the used treating parameters allowed to prepare material with the best mechanical properties and corrosion resistant. The principal parameters of materials used in the peening process are included in Table 1.…”

“…The authors emphasize that the correct selection of materials for implants or increased resistance of load bearing surfaces to wear can reduce the problem and improve the durability of applied prostheses [14]. Tribological research carried out by Żebrowski and Walczak demonstrate that printed 3D surfaces made of Ti-6Al-4V alloy and subjected to shot peening by means of steel shot and ceramic beads increase the resistance to abrasive wear in simulated in vitro conditions [26]. Furthermore, DMLS technology itself leads to the creation of residual stresses in the products.…”

“…In accordance with research carried out by authors presented in earlier studies, as a result of shot peening, shot grains penetrate (drive) into subsurface layer and, with the exception of improvement of mechanical properties, may slightly deteriorate the corrosion resistance of the modified products. Furthermore, the residuals of shot peening medium in the surface layer may contribute to elements ions release to adjacent tissues, and consequently to toxicity [28,29].…”

Objective. The aim the study was to investigate the impact of the shot peening process on the condition of the surface layer and biological properties of titanium alloy produced by means of the Direct Metal Laser Sintering (DMLS) method. Materials and method. Specimens were prepared by the EOSINT M280 metal sintering laser system. The surfaces were subjected to the shot peening process using three different media, i.e. steel shot, nutshell granules and ceramic beads, after which they were subjected to profilometric analysis, scanning electron microscopic (SEM) observations and energy dispersive X-ray spectroscopy (EDS) tests, as well as to assessment of biological compatibility in terms of cytotoxicity (SH-SY5Y cell lines). Results. The general results obtained from the tests indicate satisfactory biocompatibility of the examined surfaces and that the impact of the shot peening process on the titanium alloy cytotoxicity is acceptable. Conclusions. The lowest cytotoxicity was demonstrated by the surfaces modified by ceramic beads than the nutshells and the biggest steel shot correspondingly. Moreover, the shot peening process carried out by means of CrNi steel and ceramic shot caused the reduction of surface roughness when, for the surface processing by means of nutshell granules, the increase of surface roughness was observed compared with the unmodified surface of titanium alloy samples.

“…can improve the surface quality of the implant. For example, Zebrowski et al [151] used the shot peening method to modify the surface of the implant and explored the modification effect of different shots under different working pressures. The experimental results show that the appropriate process conditions can improve the surface quality of the implant and improve its microhardness and corrosion resistance.…”

Metals have been used for orthopedic implants for a long time due to their excellent mechanical properties. With the rapid development of additive manufacturing (AM) technology, studying customized implants with complex microstructures for patients has become a trend of various bone defect repair. A superior customized implant should have good biocompatibility and mechanical properties matching the defect bone. To meet the performance requirements of implants, this paper introduces the biomedical metallic materials currently applied to orthopedic implants from the design to manufacture, elaborates the structure design and surface modification of the orthopedic implant. By selecting the appropriate implant material and processing method, optimizing the implant structure and modifying the surface can ensure the performance requirements of the implant. Finally, this paper discusses the future development trend of the orthopedic implant.

“…Therefore, it is also important to improve the material to achieve the required hardness and fatigue resistance. For increasing the hardness of metal alloys various surface engineering processes can be used such as surface laser treatment [4,5,6], work hardening [7,8], shoot peeing [9]. The purpose of the present paper is to investigate the effect of shot peening on the state of the surface layer and corrosion resistance of specimens made of Ti-6Al-4V titanium alloy produced in Direct Metal Laser Sintering (DMLS or application of thermally sprayed coatings [10,11,12].…”

Nowadays, high-precision machines require lightweight materials with very high strength. Ion implantation is used to improve the mechanical strength of the material. A further paper presents the influence of manganese and nitrogen ion implantation on changes of microhardness of the surface layer of cobalt alloy. Samples were analyzed with the SEM-EDS Phenom ProX microscope. Microhardness was assessed with the Vickers method, and the loads of 1 gf (0.00981 N) and 5 gf (0.049 N) was applied using a FM-800 from Future-Tech microhardness meter. At a load of 1 gf, the penetration depth of the implanted specimens was reached not exceeding 0.5 um. At this depth, all samples showed an increase in microhardness compared to the unimplanted sample. The highest increase in microhardness was achieved after implantation of Mn ions with dose D=1•10 17 Mn + /cm 2 and energy E=175 keV. The increased load on the indenter to 5 gf reduced the microhardness differences between implanted and unimplanted samples.
