“…Under a load of σ max = 1050 MPa, a total number of cycles to failure N f = 224,542 cycles was determined, which subsequently increases to N f = 564,550 cycles under σ max = 950 MPa, implicating the high strength of titanium in comparison to the magnesium alloy. A general approach for testing the corrosion fatigue properties of Ti-6Al-4V is to immerse specimens for a certain time, which can be up to several weeks in SBF [6,7], and subsequently test them. As can be seen in the investigations from Liu et al [7], this can have little to no influence on the fatigue properties of Ti-6Al-4V in the HCF range.…”

“…Further on, they show good biocompatibility due to the thin oxide layer which forms rapidly on the surface [5]. Titanium alloys show in vivo and in vitro superior corrosion resistance under static loading conditions due to the presence of the passive film on the surface [6]. Even if the passive film is damaged, repassivation takes place and limits metal dissolution.…”

“…Even if the passive film is damaged, repassivation takes place and limits metal dissolution. However, it has been demonstrated that cyclic loading negatively influences the metal dissolution as well as the repassivation kinetics [6]. As a consequence, the continuous breakdown of the passive film causes localized corrosion, which leads to decreased fatigue life and, further on, toxic metallic ions are released [7].…”

Laser powder bed fusion (L-PBF) of metals enables the manufacturing of highly complex geometries which opens new application fields in the medical sector, especially with regard to personalized implants. In comparison to conventional manufacturing techniques, L-PBF causes different microstructures, and thus, new challenges arise. The main objective of this work is to investigate the influence of different manufacturing parameters of the L-PBF process on the microstructure, process-induced porosity, as well as corrosion fatigue properties of the magnesium alloy WE43 and as a reference on the titanium alloy Ti-6Al-4V. In particular, the investigated magnesium alloy WE43 showed a strong process parameter dependence in terms of porosity (size and distribution), microstructure, corrosion rates, and corrosion fatigue properties. Cyclic tests with increased test duration caused an especially high decrease in fatigue strength for magnesium alloy WE43. It can be demonstrated that, due to high process-induced surface roughness, which supports locally intensified corrosion, multiple crack initiation sites are present, which is one of the main reasons for the drastic decrease in fatigue strength.

“…Titanium and its alloy (Ti-6Al-4V alloy) are also often used as a biomaterial, since they have good mechanical properties and also good corrosion resistance [206][207][208][209][210][211][212][213][214][215][216][217]. The metal and its alloys also form thin and dense protective oxide films on it, which lead to high corrosion resistance.…”

This review describes biofilms and the need for a materials science/engineering approach to solve the problems in the medical field. In particular, biofilm problems are closely related to infectious diseases. Most chronic diseases and the hospital-acquired infections could be attributed to biofilms. Biofilms usually form on materials. They may be biomaterials such as implants, catheters, stents and others. These films can also form on items outside of the human body. They include beds, service tables, medical knives, needles for injections, etc. Even though materials obviously affect biofilms formation and growth, there have been few studies using the materials science approach. In this review, we summarize the concept of biofilms from the viewpoint of materials science. Topics include the interaction between biofilms and materials (especially metallic materials), evaluation techniques, a bird's-eye analysis of previous investigations, and a discussion about the future direction for developing anti-infectious metallic materials.

“…Electrochemical corrosion tests are valuable methods that provide qualitative and quantitative information in an accelerated manner on material degradation that normally takes a long period of time. In vitro electrochemical tests have been performed to evaluate the in vivo corrosion behavior of metallic materials with increasing importance of metallic implants with high corrosion resistance . Several types of simple solutions (simulated body fluid [SBF], Hank's balanced solution, phosphate‐buffered solution, 0.9% sodium chloride, etc.)…”

Corrosion behavior is an important parameter for metallic biomaterials used in the body environment. To mimic bodily fluids, simulated body fluid (SBF) has been used extensively. Even though many studies focus on corrosion inside SBF, SBF has a very time consuming and delicate preparation procedure and contains no essential and organic components for the cell environment, which may affect corrosion kinetics. We aimed to investigate whether corrosion behavior or kinetics change in different solutions, SBF and Dulbecco's modified Eagle medium (DMEM). For this purpose, five commonly used metallic biomaterials, AISI 316 stainless steel, CoCrMo alloy, CP‐Ti, Ti6Al4V, and Ti6Al7Nb were subjected to open circuit measurements, cyclic polarization, and electrochemical impedance spectroscopy. Quantitative analyses were performed and surface topography was investigated via scanning electron microscope and a roughness tester. We observed that the materials exhibited similar behaviors in SBF and DMEM but the corrosion kinetics were somewhat different and the results obtained from DMEM were time dependent.
