“…Inhibiting species such as chromate, molybdate, tungstate, cerium, and silicate ions, may also be incorporated in the passive fi lm by surface treatments leading to a more corrosion resistant material (Breslin et al, 1997;Gluszek et al, 1985). These techniques have been proven useful in several SS of the 300 series.…”

“…These anions may inhibit pitting corrosion by changing the anion selective character of the passive fi lm to cation selective, preventing the ingress of chloride ions (Sakashita & Sato, 1978 (Gluszek et al, 1985). It has been proposed that chromate, molybdate, and tungstate ions are reduced forming dense precipitates that function by an ohmic blocking action (Ilevbare & Burstein, 2003;Newman & Ajjawi, 1986).…”

“…Their effi ciency seems to be related to the ability to form a hemimicellar layer on the passive fi lm surface (DeBerry & Vielbeck, 1988). Inhibiting species may also be incorporated on the passive fi lm by proper surface treatments (Breslin, Chen, & Mansfeld, 1997;Gluszek, Freeman, Baron, & Kubicki, 1985). Pitting corrosion may be photoinhibited by illumination with ultraviolet (UV) light (Fujimoto, Yamada, & Shibata, 1998;MacDonald & Heaney, 2000;MacDonald, Sikora, Balmas, & Alkire, 1996).…”

“…They may also act by local pH buffering (DeBerry & Vielbeck, 1988). Inhibiting species incorporated to the passive fi lm by surface treatments may form thicker and more protective fi lms (Gluszek et al, 1985), may reduce the oxygen reduction kinetic on the fi lm (Breslin et al, 1997), or may act by a specifi c action in the pit nucleation sites . Photoinhibition of pitting corrosion by UV illumination is attributed to the modifi cation of the passive fi lm, the electric fi eld in the fi lm, and changes in the electronic structure on the fi lm/solution interface (Fujimoto et al, 1998;MacDonald & Heaney, 2000;MacDonald et al, 1996).…”

“…The deposition of the reduction products (Cr 2 O 3 and MoO 2 ) is also proposed as an inhibiting mechanism. Cr 3 + and Mo 4 + may be built into the fi lm (Devasenapathi & Raja, 1996;Gluszek et al, 1985;Sugimoto & Sawada, 1976;Zuo et al, 2002).…”

The application of stainless steels and chromium containing nickel-based alloys is limited by their susceptibility to localized corrosion in the forms of pitting and crevice corrosion or environmentally assisted cracking. Inhibitors may be normally found in service environments or added on purpose to mitigate or avoid the effects of aggressive agents such as chloride ions. The present study critically reviews the present knowledge on inhibition of chloride-induced pitting and crevice corrosion. Pioneering studies and recent fi ndings are analyzed in light of the present theories for describing the localized corrosion processes. This review particularly focuses on the inhibition of crevice corrosion of alloy 22, which has been thoroughly studied in the past decade.

Auger electron spectroscopic (AES) studies were conducted to examine the surface film of stainless steel specimens which had been subjected to passive and anodic corrosion in vitro and in vivo. Anodic corrosion was accelerated by the application of a +500 mV (SCE) potential for 30 minutes. Experiments performed in 0.9% saline indicated little alteration in the nature of the surface film compared to a freshly prepared control specimen. Auger analysis of specimens in 10% serum or in vivo revealed that passive film thickness was dependent on the corrosive environment. The films of specimens immersed under freely corroding conditions in 10% serum or in vivo were similar to the control film. Accelerated corrosion performed in 10% calf serum resulted in significant film thickening. The thickest films were from accelerated corrosion in vivo. The mechanism for the altered surface films produced by corrosion in vivo or in serum as compared to saline needs to be investigated further.

Orthodontic stainless-steel appliances are considered to be corrosion resistant, but localized corrosion can occur in the oral cavity. This study was undertaken to evaluate the properties of super stainless steels in orthodontic applications. Accordingly, the metallurgical properties, mechanical properties, corrosion resistance, amount of the released nickel, cytotoxicity, and characteristics of the passive film were investigated. Corrosion resistances of the specimens were high and in the following order: super austenitic stainless steel (SR-50A) > super ferritic stainless steel (SFSS) = super duplex stainless steel (SR-6DX) > 316L SS > super martensitic stainless steel (SR-3Mo) in artificial saliva, 37 degrees C. At 500 mV (SCE), current densities of SR-50A, SFSS, SR-6DX, 316L SS, and SR-3Mo were 5.96 microA/cm(2), 20.3 microA/cm(2), 31.9 microA/cm(2), 805 microA/cm(2), and 5.36 mA/cm(2), respectively. Open circuit potentials of SR-50A, 316L SS, SR-6DX, SR-3Mo, and SFSS were - 0.2, - 0.22, - 0.24, - 0.43, and - 0.46 V (SCE), respectively. SR-50A, SFSS, and SR-6DX released below 3 ng/ml nickel for 8 weeks, and increased a little with immersion time, and 316L SS released about 3.5 ng/ml nickel, but SR-3Mo released a large amount of nickel, which increased with immersion time. The study demonstrated that SR-50A, SR-6DX, and SFSS have high corrosion resistance and mild or no cytotoxicity, due to the passive film enhanced by synergistic effect of Mo + N or by high addition effect of Cr + W. All super stainless steels showed very low cytotoxicity regardless of their nickel contents, although SR-3Mo was found to be relatively cytotoxic. From these studies, these steels are considered suitable for orthodontic applications.
