“…In vivo experiments have shown that nickel ions are released, which leads to poor resistance and adverse reactions to the biological system. For this reason, an alternative has been found to avoid this disadvantage by introducing a new type of Co-Cr alloys [78][79][80].…”

Biomaterials and their use as implant coatings have been evaluated focusing on biocompatibility, biodegradability and constructive responses in terms of osseointegration, cell proliferation and cell adhesion. Biomaterials from natural (protein and polysaccharide) and synthetic (metallic, polymeric, ceramic and composite) sources have been identified. The role of biomaterials and implant coatings in the body through in vivo and in vitro experiments has been highlighted. In addition, methods for activating the surface of implants such as mechanical, chemical and physical ones are presented, as well as the classification of the deposition procedures but also of the interactions with the living system. This review addresses a topic with future challenges and perspectives in the biomedical field with the well-defined goal of maintaining and enhancing tissue elasticity, facilitating the healing of diseases suffered by patients and developing innovative materials capable of replacing or regenerating affected tissues.

With numerous reinforcements, aluminum and its alloys are finding growing applications in every sector of industry. Titanium carbide (TiC) is regarded as an outstanding reinforcing material as compared to widely used carbide particles because of its excellent physical and mechanical characteristics, as well as its especially good interfacial bonding (wetting) capacity with aluminum. In the present research work, the effect of the mixing time of the matrix and reinforcement powders has been investigated on the crystallite size and lattice strain of the AA7075–5 wt.% TiC composites. The mechanical properties of the developed composites were also investigated in terms of microhardness values. X‐ray diffraction and scanning electron microscopy (SEM), transmission electron microscopy (TEM), particles size distribution analysis and x‐ray energy dispersive spectroscopy (EDS) of the synthesized powder samples were done to see the effect of mixing time on their microstructures. The increase in mixing time led to a homogeneous distribution of 5 wt.% of TiC particles, a decrease in particles clustering. The considerable grain refining was confirmed, which reflected a reduction in particle size originating from a prolonged mixing time. The significant improvement in the crystallite size and microhardness of the produced composites were achieved with increasing mixing time.

“…The foremost commonly utilized biomaterials include Ti6Al4V, CoCrMo, and AISI 316L stainless steel [14]. Owing to its low cost, reasonable corrosion resistance, and ease of manufacturing, one of the most frequently used biomaterials in the manufacturing of implants is austenitic 316L stainless steel, the commercially available biomaterial [15,16]. The implants manufactured from this material are cheaper than titanium and cobaltbased alloys by one-tenth to one-fifth [17,18].…”

“…To increase the performance of this material, the behaviour of simultaneous additions of boron, titanium, and niobium in stainless steel alloy can be examined. For producing a protective surface layer, consolidation factors such as compaction pressure, sintering temperature, and dwell time have not been explored in our previous studies [15,25,38,[40][41][42][43]. This research work examines the effect of material composition on the physical and mechanical properties of modified 316L stainless steel alloy.…”

AISI 316L stainless steel (SS) is one of the extensively used biomaterials to produce implants and medical devices. It provides a low-cost solution with ample mechanical properties, corrosion resistance, and biocompatibility compared to its counterpart materials. However, the implants made of this material are subjected to a short life span in human physiological conditions leading to the leaching of metal ions, thus limiting its use as a biomaterial. In this research, the addition of boron, titanium, and niobium with varying concentrations in the SS matrix has been explored. This paper explores the impact of material composition on modified SS alloy’s physical and mechanical properties. The study’s outcomes specify that the microhardness increases for all the alloy compositions, with a maximum increase of 64.68% for the 2 wt.% niobium added SS alloy. On the other hand, the tensile strength decreased to 297.40 MPa for the alloy containing 0.25 wt.% boron and 2 wt.% titanium additions compared to a tensile strength of 572.50 MPa for pure SS. The compression strength increased from 776 MPa for pure SS to 1408 MPa for the alloy containing niobium and titanium additions in equal concentrations.
