“…This revealed that most of the corrosion damage occurred within the region that experienced a compressive load in comparison to the region which experienced a tensile load. The compressive and tensile regions analysed showed that the compressed regions had a 3 times increase in corrosion, which was an interesting observation as many studies which correlate mechanical stress to accelerated corrosion commonly reference crack initiation and propagation under tensile loads or fatigue [14,16,24,34]. Studies which focus on mechanical corrosion have commented extensively on tensile testing and increasing hair line cracks which can lead to crack propagation that is accelerated under a corrosive environment [24].…”

Stainless steel is used extensively within orthopaedics as part of varying surgical procedures such as trochanteric osteotomy, sternum closure, patella tendon repair and reconstruction, patellofemoral ligament reconstruction and internal fracture fixation. This study examines the changes in corrosion behaviour after applying plastic and elastic stresses. Furthermore it analyses how a tensile and a compressive load can affect the corrosion susceptibility of a material. Stainless steel test specimens were divided into three groups of seven to determine how corrosion susceptibility will change when a material is prestressed. Potentiodynamic testing was performed to investigate the pitting behaviour of ss304 after being exposed to pre-stressed conditions. All images graded exhibited both area and pit corrosion scores, which significantly differed between the 3 groups (p \ 0.001). The samples that were destructively stressed under compression had a mean of 35.5 % corrosion damage (SD 14.5) which is significantly greater (p = 0.001) compared to a mean of 11 % (SD 4.5) corrosion damage present with a material destructively stressed under tension. This study has shown that a material's corrosion susceptibility changes significantly after being pre-stressed regardless, whether this is mechanically loading it within its yield strength or destructively loading.

“…To better describe the YS and UTS here, permissible strain, another significant design parameter for orthopedic implants defined as the ratio between YS and UTS, was applied 37 . This parameter should be larger than that for human cortical bone (0.67) 37 . Among these 5 alloy systems, TAV, cp-Ti and TNTZ are larger than criteria.…”

We developed an osseocompatible β-type Ti-28Nb-11Ta-8Zr (TNTZ) alloy that displays the excellent elastic modulus, cellular response, corrosion resistance and antibacterial capability demanded for bone-mimetic materials. The TNTZ alloy exhibited an elastic modulus of 49 GPa, which approximates that of human bones and prevent stress shielding effects. A further anodic oxidation and subsequent post-annealing modification formed a crystalline nanoporous TNTZ oxide layer (NPTNTZO(c)) on the alloy surface, potentially promoting interlocking with the extracellular matrix of bone cells and cell proliferation. Osteoblast viability tests also verified that NPTNTZO(c) enhanced cell growth more significantly than that of flat TNTZ. In addition, potentiodynamic polarization tests in Hanks’ balanced salt solution (HBSS) revealed that both TNTZ and NPTNTZO(c) exhibited better corrosion resistance than commercial pure titanium. Finally, NPTNTZO(c) reinforced with silver nanoparticles (NPTNTZO(c)/AgNPs) intensified the antibacterial efficiency against Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli for 8 h with antibacterial efficiencies of 87.82%, 97.68%, and 93.90%, respectively, facilitating infection prevention during surgery and recovery stages.

“…Titanium alloys have been studied in different physiological mediums, such as artificial saliva, Hank solution, Ringer solution, NaCl solution to understand their electrochemical behavior as biomaterials subjected to corrosion in human organism [16][17][18][19][20]. In some studies, the influence of molybdenum content on corrosion resistance of Ti-Mo alloys in different simulated physiological environments has been investigated and one showed that the electrochemical behavior was improved due to the presence of molybdenum [21][22][23][24][25][26]. The superior properties of Ti-Nb and Ti-Nb-Zr systems are ascribed to addition of niobium (Nb) as the primary alloying element since it possesses distinguish attributes of improved β stability, low elastic modulus and high corrosion resistance [27][28][29][30][31][32][33][34][35][36].…”

The aim of this study was to investigate the influence of different process parameters as chemical composition, the pH value and immersion time on the corrosion of the some TiMoNb alloys, using different electrochemical techniques such as: cyclic voltammetry, open circuit potential (OCP) measurement, polarization curves and electrochemical impedance spectroscopy (EIS). The alloys were analyzed in the natural pH of the Ringer solution, but also with an acidic modification of the solution (ph = 4) and a basic modification (ph = 8). The more acidic values of pH, the more evident are differences between corrosion behavior of titanium-based alloys depending on their chemical compositions and immersion times.
