“…However, the natural oxide grown spontaneously on the Ti alloys was around 2.0 nm in thickness (Marino et al, 2001). The voltammogram of the ISO 5832-9 stainless steel showed the growth of a thin layer of around 3.0nm, which is comparable to the natural oxide (Hanawa et al, 2002;Yi et al, 2013). Many studies have shown that chemical treatments of the metal surfaces increase the ability for bone growth around the implant, due to better chemical interaction between the elements in the interface (Yang et al, 2004;Yu et al, 2010).…”

Introduction: Titanium alloys and seeveral stainless steels show good performance when used in orthopedic replacements due to their excellent properties, such as mechanical strength and corrosion resistance. The aim of this study was to evaluate the implant-bone interface on ISO 5832-9 and Ti6Al4V alloys electrochemical treated. Methods: The growth of oxides was carried out on stainless steel ISO 5832-9 up to1.0V in phosphate buffered saline and Ti6Al4V alloy up to 5.0V, at room temperature. Scanning electron microscopy (SEM) was used for qualitative characterization. The in vivo experiment was conducted with rats divided into 3 groups: untreated surface-Control (Group 1); anodic oxide grown up to 1.0V for ISO 5832-9 and up to 5.0V for Ti6Al4V (Group 2); anodic oxide grown up to 1.0V for ISO 5832-9 and up to 5.0V for Ti6Al4V and surface activation with hydroxyapatite (Hpa) in SBF (10 days) for both materials (Group 3). The implants were inserted in tibia by surgery. After 6 weeks the animals were euthanized and tibia processed for SEM. Results: Ti6Al4V alloy had a typical valve's metal behaviour due to stable oxide titanium growing as barrier. ISO 5832-9 stainless steel showed stable oxide but as a thinner film irregularly distributed on the surface of implants. These behaviours were consistent with in vivo test which showed uniform bone matrix deposition on the Ti6Al4V surface of bone

“…2a). 40 In the potentiodynamic polarization curves of grain boundary etched and electro-polished SS316L samples, no characteristic metastable localized corrosion was observed; passivity was observed at potentials up to 0.9 V. Beyond the passivity region, stable localized corrosion occurred for the grain boundary etched and the electro-polished SS316L samples in fairly narrow potential ranges: 0.96 to 1.05 V for grain boundary etched, and 0.99 to 1.07 V for electro-polished samples (Figs. 2b, 2c).…”

“…These curves display onset points of SS316L sample dissolution, passivity, and rapid increases in current density due to localized corrosion. 37,40 Since the SS316L samples were polarized in the anodic direction from open circuit conditions, the starting point of each curve represents the open circuit potential (E OC ). The sharp increase in current density at high potential (i.e.…”

Localized corrosion of stainless steels by chloride ions in seawater leads to metal degradation while fouling of marine organisms increases the occurrence of localized corrosion. We describe a simple method to increase hydrophobicity of austenitic stainless steel using grain boundary etching that can also inhibit adhesion of bio-organisms present in seawater as well as increase the localized corrosion resistance of stainless steel in chloride-containing aqueous environments. This paper describes the corrosion behavior of stainless steel as a result of grain boundary etching to achieve hydrophobicity. Potentiostatic polarization on stainless steel 316L in a nitric acid solution at an anodic potential of 1.3 V vs. saturated calomel electrode (SCE) results in a grain boundary etched structure and a Cr-and Mo-rich passive film as confirmed by scanning electron microscopy and X-ray photoelectron spectroscopy. This modified stainless steel 316L surface exhibits enhanced corrosion resistance to a 0.6 M sodium chloride solution. Specifically, potentiodynamic polarization studies indicate that the breakdown potential increases and the sample-to-sample variability decreases. Due to the ubiquitous use of metals in infrastructure, production and manufacturing, transportation, and utilities, corrosion results in compromised safety and recurring repair costs.1 One of the most commonly employed approaches to control corrosion is the use of corrosion resistant alloys.1 Stainless steels (SSs), which are defined as steel alloys containing at least 10.5% chromium content by mass, are the most frequently used materials in aqueous environments because of their enhanced corrosion resistance relative to carbon steels. 2Chromium participates in the formation of a stable passive film on SSs that protects the bulk metal against corrosion.3 However, SSs still suffer from localized corrosion when exposed to chloride-containing aqueous environments, including seawater 4,5 and bleach plants associated with pulp and paper industries. Strategies to improve the localized corrosion resistance of SSs include enrichment of Cr and Mo at the SS surfaces and removal of surface inhomogeneities.7 These SS surface treatments include mechanical polishing, 8,9 passivation, 7,9-11 and electro-polishing. 8,[12][13][14] Mechanical polishing results in Cr-rich SS surfaces. 9 Surface passivation of SS using a nitric acid solution removes surface inhomogeneities and enhances the formation of a Cr-rich passive film. Electro-polishing is a technique to control the surface finish of a metal by anodic electrochemical dissolution to yield a smooth metal surface. Electro-polishing removes surface inhomogeneities from the SS surface and simultaneously forms Cr-and Mo-rich passive films. Electropolished SS surfaces show higher localized corrosion resistance than mechanically polished and passivated SS surfaces.14 Chromium oxide/hydroxide (Cr 2 O 3 /Cr(OH) 3 ) in the passive film hinders movement of cations into the electrolyte and thereby delays local breakdown of the ...

“…The chloride ion is highly electronegative and very reactive with specific compounds and elements. The polarization behavior in chloride ioncontaining solution has been investigated for decades and a number of conclusions on its electrochemical influence on the pitting corrosion mechanism have been reached [34][35][36][37][38][39][40][41]. In this chapter, the pitting corrosion resistance of type 301, 304 and 316 austenitic stainless steels exposed to 2 M H 2 SO 4 acid at specific chloride concentrations will be discussed with focus on the potentiodynamic polarization behavior of the steels, characterization of the pitting susceptibility of the steels in the environments under study, metastable pitting, influence of chloride ion concentration and inhibitor protection through the use of rosemary oil and aniline.…”

The pitting corrosion behavior of 301, 304 and 316 austenitic stainless steels in 2M H 2 SO 4 at 0-1.5% NaCl concentrations was investigated through potentiodynamic polarization and optical microscopy analysis. Electrochemical analysis of the pitting corrosion inhibition and surface protection properties of rosemary oil and aniline on the stainless was also performed. The corrosion rate, pitting potential, passivation potential, metastable pitting potential and surface morphology of both steels where significantly altered by changes in chloride concentration, differences in alloy composition and metallurgical properties of the steels. 316 steel had the lowest corrosion rate and highest pitting corrosion resistance followed by 301 steel. The surface morphology of 316 steel was slightly altered at 1.5% NaCl concentration while 301 steel appears to etch with grain boundaries appearing at higher chloride concentration. 304 steel showed no resistance to pitting after 0% NaCl coupled with relatively significant increase in corrosion rate values. Its surface morphology showed the presence of corrosion pits with respect to chloride and inhibitor concentration. Rosemary oil and aniline significantly reduced the corrosion rates values of the stainless steels and with consequent increase in their pitting corrosion resistance; however the compounds had no positive influence on the pitting corrosion behavior of 304 steel.
