“…2, the E corr in PBS?BSA are more negative than those in PBS invariably at any point in time, and the results suggest that the addition of BSA increases the corrosion tendency of the TLM alloy. The results are consistent with the results of C. Valero et al [29] and Cheng et al research [30]. BSA acts as inhibitor of the cathodic process and accelerates the anodic reaction.…”

“…BSA acts as inhibitor of the cathodic process and accelerates the anodic reaction. The inhibition influence can be explained by the presence of adsorbed BSA that may impede the access of the oxidant to the metallic surface [29,30]. For another, the adsorption of the protein can bind to metal ions and transport them away from interface between the solution and passive film [31].…”

“…The corrosion current density is the same order of magnitude in different solutions, and the value of i corr in PBS?HA is the biggest. HA has higher viscosity, when it was adsorbed on the surface of the TLM alloy, it would refrain the diffusion of O and Ti ions, reduce the rate of oxygen reduction reaction and slow down the speed of the formation of the passive film on the surfaces of the samples [30]. Without the protection of the passivation film, the corrosion rate would increase in PBS?HA.…”

“…The effect was most dramatic with the addition of HA (Table 3). It is well known that many organic corrosion inhibitors prevent corrosion by forming an adsorbed film and blocking the mass transportation during the process of corrosion; the proteins have high affinity for adsorption onto metal alloy surfaces [30].…”

Wear and Electrochemical Corrosion Behavior of Biomedical Ti–25Nb–3Mo–3Zr–2Sn Alloy in Simulated Physiological Solutions

The wear and electrochemical corrosion behavior of the biomedical Ti-25Nb-3Mo-3Zr-2Sn (TLM) titanium alloy was investigated in various simulated physiological solutions. Different simulated physiological solutions comprised phosphate-buffered solution (PBS), PBS with bovine serum albumin (PBS?BSA), and PBS with hyaluronic acid (PBS?HA) were employed. A potentiostat and a reciprocating friction and wear tester were used to study the wear and corrosion behavior of the TLM alloy. The influence of the chemical composition of the simulated solutions on the tribo-electrochemical behavior was considered by potentiodynamic studies under reciprocating friction and wear conditions. It was found that the corrosion tendency of the TLM alloy was the most obvious in PBS?HA under static corrosion condition, while it was just opposite with wear. Compared with static corrosion, the corrosion resistance of the TLM alloy was decreased with sliding conditions. The values of i corr were two orders of magnitude higher than those at static corrosion. This phenomenon shows that the wear accelerated corrosion. Under coexisting condition of both electrochemical corrosion and wear, the wear rate of the TLM alloy mutually influenced by both factors will be accelerated. Plastic grooves and deformation were observed on the worn surfaces of the TLM alloy by scanning electron microscopy (SEM). Through the observation of SEM, the tribological mechanism was a typical corrosive wear, and the main wear mechanisms were abrasive with adhesive wear under the interaction between corrosion and wear. The XPS results show that the passive films include the TiO

The interaction of bovine serum albumin (BSA) protein with copper in phosphate buffer solution has been studied by a combination of electrochemical impedance spectroscopy (EIS) close to the open circuit potential, with simultaneous monitoring by the electrochemical quartz crystal microbalance (EQCM), in order to throw light on BSA adsorption. Copper films were electroplated onto gold quartz crystals and mounted in the EQCM. Experiments were conducted in the presence and absence of dissolved oxygen and of BSA and the results show the influence of O 2 on the protein/metal interaction and also show specific interactions between BSA and copper. The good reproducibility obtained in these experiments suggests future application to other systems and which should lead to a better understanding of the use of such types of protein as corrosion inhibitors.

Elaboration of Monophasic and Biphasic Calcium Phosphate Coatings on Ti6Al4V Substrate by Pulsed Electrodeposition Current

et al. 2010

View full text Add to dashboard Cite

Calcium phosphate coatings on Ti6Al4V substrates are elaborated by pulsed electrodeposition. The surface morphology and chemical composition of the coatings are characterized by SEM–EDS. The obtained results are systematically confirmed at the nanometre scale using TEM. Moreover, XRD is performed in order to identify the coatings phases. The results show that pulsed electrodeposition allows uniform coatings to be obtained without the holes and craters usually observed with classical electrodeposition. After appropriate heat treatment, these coatings have a biphasic composition of stoichiometric hydroxyapatite and β‐tricalcium phosphate. Moreover, the addition of 9% H2O2 to the electrolyte leads to monophasic coatings made of stoichiometric hydroxyapatite. As an indication of the passive nature of the electrodeposited coating, electrochemical potentiodynamic tests are performed in physiological solution in order to determine the corrosion behaviour of these coatings.
