Corrosion resistance of pulsed laser-treated Ti–6Al–4V implant in simulated biofluids

A novel proposal to manipulate the properties of titanium parts by laser surface alloying

“…The main objective of surface modification is the improvement of wear and corrosion resistance [3,4]. In the specific case of biomaterial applications, bioactive layers [5] serve to increase the material's biocompatibility, and osseointegration can be enhanced by producing greater surface roughness or even porosity [6].…”

Inhibiting and healing effects of potassium permanganate for silane films

“…Tafel low-polarization analysis is a well-established electrochemical technique, in which a typical potential scan of ±50 mV around the open circuit voltage is imposed on this coating system [21]. The Tafel plots are shown in Fig.…”

Role of Proteins on the Electrochemical Behavior of Implanted Metallic Alloys, Reproducibility and Time-Frequency Approach from EIS (Electrochemical Impedance Spectroscopy)

“…From this useful kind of investigations, two time constants were highlighted on the Ti-6Al-4V alloy: the first layer is the thickness of oxides and the second one is the adsorbed proteins (Pan, 1996;Tamilselvi, 2006). When a solution constituted by phosphate ions, from PBS solution, and proteins, the equivalent electrical circuit with two constant times fits well (Zaveri, 2008). A competitive adsorption does exist between the one of phosphate ions and the one of proteins.…”

“…A competitive adsorption does exist between the one of phosphate ions and the one of proteins. Consequently the EIS measurements could be interpreted differently due to close experimental conditions but the reproducibility is not studied (Ouerd, 2007;Zaveri, 2008)). To conclude on this part, it is worth noting that the quantity of the adsorbed proteins was investigated.…”
