“…According to ASTM F756-08 [61], materials with hemolysis up to 5% are considered highly hemocompatible. In this study, although some compositions showed slightly higher rates than others, all of them were considered highly hemocompatible, as seen in previous studies [59,62]. Even if the literature indicates that both 316L stainless steel and β-TCP have good wettability and hemocompatibility, this indication is not related to materials produced by powder metallurgy.…”

Metallic biomaterials are widely used for implants and dental and orthopedic applications due to their good mechanical properties. Among all these materials, 316L stainless steel has gained special attention, because of its good characteristics as an implantable biomaterial. However, the Young’s modulus of this metal is much higher than that of human bone (~193 GPa compared to 5–30 GPa). Thus, a stress shielding effect can occur, leading the implant to fail. In addition, due to this difference, the bond between implant and surrounding tissue is weak. Already, calcium phosphate ceramics, such as beta-tricalcium phosphate, have shown excellent osteoconductive and osteoinductive properties. However, they present low mechanical strength. For this reason, this study aimed to combine 316L stainless steel with the beta-tricalcium phosphate ceramic (β-TCP), with the objective of improving the steel’s biological performance and the ceramic’s mechanical strength. The 316L stainless steel/β-TCP biocomposites were produced using powder metallurgy and functionally graded materials (FGMs) techniques. Initially, β-TCP was obtained by solid-state reaction using powders of calcium carbonate and calcium phosphate. The forerunner materials were analyzed microstructurally. Pure 316L stainless steel and β-TCP were individually submitted to temperature tests (1000 and 1100 °C) to determine the best condition. Blended compositions used to obtain the FGMs were defined as 20% to 20%. They were homogenized in a high-energy ball mill, uniaxially pressed, sintered and analyzed microstructurally and mechanically. The results indicated that 1100 °C/2 h was the best sintering condition, for both 316L stainless steel and β-TCP. For all individual compositions and the FGM composite, the parameters used for pressing and sintering were appropriate to produce samples with good microstructural and mechanical properties. Wettability and hemocompatibility were also achieved efficiently, with no presence of contaminants. All results indicated that the production of 316L stainless steel/β-TCP FGMs through PM is viable for dental and orthopedic purposes.

“…The nanostructured PMMA-BG61-MSS demonstrated good adhesion, durability, and peeling resistance, and served as an efficient shield against corrosion without affecting bioactivity and biocompatibility [54]. In a study, Fe-based steel electrode (Fe37Cr15Mo2B26C7Nb3Si3Al6Mn1) was deposited on MSS using the electro-spark deposition (ESD) method and reported to develop a uniform, dense, and optimum rough surface that shows biocompatibility and hemocompatibility [117]. Bioactive HA-titania (TiO 2 ) deposited and embedded in an MSS substrate using a combined laser-sol-gel technique was found to be bioactive and biocompatible [43].…”

Medical-grade stainless steel (MSS) is one of the most widely used materials for implantable devices in biomedical applications, including orthopedic stents, dental implants, cardiovascular stents, cranial fixations, and surgical suture materials. Implants are exposed to corrosive body fluids containing chlorides, proteins, and amino acids, resulting in corrosion, wear, toxicity, inflammation, infection, and failure. MSS-based materials exhibit improved corrosion and mechanical resistance and suppress the degradation and release of toxic metal ions. Although MSS is manufactured with a passivating metal oxide layer, its anti-corrosion performance against chlorides and chemicals in body fluids is insufficient. Implants require biocompatibility, bioactivity, hemocompatibility, and sustainability. Antimicrobial activity and sustained drug release are also crucial factors. Therefore, stainless steel with desirable multifunction is in great clinical demand. This comprehensive review summarizes recent advances in the surface modification of MSS-based implants and their biomedical applications, especially in dentistry.

“…Subsequently, the alloy is converted to an amorphous or bio-metallic glass structure through J o u r n a l P r e -p r o o f heating and subsequent rapid cooling, sufficient to avoid crystallisation (Figure 6). Thus, the structural amorphous features of the material coupled with the flexible elemental compositions produce different forms of BMGs for specific functions like biomaterials [150][151][152], catalysis [153], antibiosis [154], magnetic [155][156][157] and structural materials [30,143]. The essential consideration during the formation of biomedical BMGs largely depends on the non-toxicity and biocompatibility, GFA, as well as physical and mechanical behaviour of the alloying elements.…”
