“…The effect of proteins on iron released from stainless steels (or generally on corrosion behaviour of stainless steels) has been much more frequently studied than in the case of pure iron, 17,18,[28][29][30][31][32] as stainless steels already nd applications in biomedicine (and in other applications, where proteins are of relevance). However, as the surface chemistries of stainless steels and iron are far from identical, the relevant protein-induced metal release mechanisms may vary considerably for the two materials.…”

Protein interactions with corroding metal surfaces: comparison of Mg and Fe

et al. 2015

The influence of bovine serum albumin (BSA) on the electrochemical behaviour of pure Mg and Fe was studied in simulated body fluid (SBF), in view of the possible application of these materials as biodegradable metals. Results indicate a different trend for the BSA-effect on corrosion for the two metals: for Mg, a strong corrosion-inhibiting effect is observed in the presence of BSA in solution, especially for short-term exposure, whereas for Fe only a slight acceleration of corrosion is caused by the addition of BSA to the solution. For both metals, the protein-effect on the electrochemical behaviour shows a complex time-dependence. Surface analysis indicates that stronger BSA adsorption takes place on Mg than on Fe. Moreover, adsorption experiments with BSA and a second protein (lysozyme) were conducted. The results are discussed in view of electrostatic interactions between differently charged metal oxide/hydroxide surfaces and proteins.

“…This work focuses on albumin, which is the main protein of blood plasma. Afonso et al [13] have shown that bovine serum albumin, in NaCl 0.15 M at 37 °C, on UNS S31254 stainless steel, stops anodic dissolution of chromium and decreases iron dissolution. Valero Vidal et al [14] worked with 316L and CoCrMo alloy in NaCl 0.14 M at 37 °C, with or without albumin (0.5 g.L -1 ).…”

In biomedical field, fretting-corrosion between 316L SS femoral stem and bone cement is one of the significant causes of the hip prosthesis loosening. This article investigates wear by fretting-corrosion at the contact between 316L and PMMA . The influences of the ionic strength (NaCl solutions from 10 -3 to 1 mol.L -1 ), a model protein (albumin) and electrochemical conditions on contact behaviour are studied. At OCP (Open Circuit Potential) conditions, the chlorides concentration, i.e. the ionic strength, increases the 316L wear; and albumin, concentration of 1g.L -1 , does not play a significant role in total 316Lwear. At cathodic applied potential E = -400 mV(SCE), a threshold concentration of 10 -1 mol.L -1 (NaCl solution), C th , indicates two behaviours: a protective effect below C th , and an additional anodic dissolution above C th . One might suggest that, beyond C th , the passive layer is not efficient for protecting against the corrosion. At this potential, albumin reduces wear due to corrosion and amplifies mechanical wear induced by corrosion. Albumin seems to act as an anodic inhibitor. To determine the mechanisms of synergism, a "more cathodic" potential is applied, E = -800 mV(SCE), during fretting-corrosion experiments.Consequently, the corrosive wear can be neglected and the mechanical wear can be only measured.

“…Likewise, UNS S31254 SS (254 SS) also exhibits high resistance against hydrochloric acid [9] and phosphoric acid [10], and in chloride media it does not exhibit pitting at room temperature [9]. Absence of toxic effect as confirmed by cytotoxicity results and high nitrogen content of 254 SS have made it a candidate material for scientific investigation, towards developing futuristic implant materials [11][12].…”

“…Lately, newer generation of steels with superior corrosion resistance and mechanical properties are being studied [3][4][5][6][7]. For orthopaedic implants ISO 5832-9 SS is being used, in comparison to F138-92 SS as it does not undergo pitting corrosion [8][9][10][11][12]. Likewise, UNS S31254 SS (254 SS) also exhibits high resistance against hydrochloric acid [9] and phosphoric acid [10], and in chloride media it does not exhibit pitting at room temperature [9].…”

Hydroxyapatite (HA) is popularly used as a bio-compatible coating material for metallic implants, in view of its improved bone fixation property, leading to an increased life of the implant. However, the deposition of HA on medical grade UNS S31254 stainless steel (SS254) for orthopaedic implant applications by the radio-frequency magnetron sputtering technique is unreported in the literature so far. The surface morphology of deposited HA coatings was characterized using Scanning Electron Microscopy and Atomic Force Microscopy, while their phase composition was determined using X-ray Diffraction. The thickness and adhesive strength of the HA coatings were determined using an Ellipsometer and a Tensometer, respectively. Finally, the antibacterial efficacy and bioactivity of the deposited coatings were confirmed using Fluorescence Activated Cell Sorting and Immersion test in Simulated Body Fluid environment. The obtained results showed that the HA coatings grown on SS254 using magnetron sputtering possess desirable surface properties as well as adhesion and biocompatibility properties, ideally suited for potential applications in orthopaedic implants.
