This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a study of the crevice corrosion behaviour of commercially pure titanium, Ti Grade-2 (Ti-2), and two Ti dilute alloys, Ti Grade-12 (Ti-12, Ti-0.8Ni-0.3Mo), and Ti Grade-7 (Ti-7, Ti-0.15Pd) in air saturated 0.27 mol/dm3 NaCI solution using a galvanic coupling technique. Various aspects of the crevice corrosion process were studied to understand the primary factors that influence titanium's susceptibility to this form of corrosion and to determine the conditions under which crevice attack is possible. First, the temperature dependence of crevice corrosion initiation and propagation on Ti Grade-2 has been studied in detail. Crevice corrosion experiments in which the temperature was increased and decreased in steps over the temperature range 55 degrees C to 95 degrees C have identified a temperature threshold of 65 degrees C for the initiation of crevice corrosion. This is based on the onset (increasing temperature) and disappearance (decreasing temperature) of film breakdown/repassivation microtransients generated inside the crevice. Consistent with the initiation of crevice corrosion, the passive film resistance dropped significantly at T>: 65 degrees C accompanied by water incorporation into the oxide film. Early initiation occurred at individual sites around the edge of the crevice, and the acidity that consequently developed spreads towards the central region of the crevice. Then, the microstructure and crevice corrosion behaviour of three Ti-2 materials containing different levels ofFe as impurity (0.04 - 0.12 wt%), were studied. The grain size decreased significantly with increasing iron content. Crevice corrosion was initiatedon all three materials at 70 ± 5 degrees C. Crevice corrosion of Ti-2 with an Fe content of 0.078 wt% (medium Fe content) was initiated at the lowest temperature and exhibited extensive intergranular attack due to the accumulation ofFe in the grain boundaries. Ti-2 with a low iron content (0.042 wt%) was free of intergranular attack. By contrast, corrosion damage was more localized along the periphery of the crevice for Ti-2 with an Fe content of 0.12 wt% (high Fe content), and the crevice corrosion resistance was greatly enhanced. By performing a series of crevice corrosion experiments combined with metallographic and image analysis techniques on Ti-2 with Fe 0.078 wt%, a damage function relating the maximum penetration depth to the duration of propagation was developed for crevice corrosion. The damage function showed two distinct stages. In the first stage, penetration was rapid due to the intergranular nature of the penetrating front on this material. On the second stage, penetration was greatly limited by IR (ohmic) effects at the corroding sites. Thirdly the crevice corrosion behaviour of Ti-12 was studied. Crevice corrosion on Ti-12 initiated a similar temperature to that observed for Ti-2, -70 degrees C, but showed a higher resistance to crevice propagation. The propagation process was independent of temperature. The crevice attack appeared in the form of rectangular-shaped pits with limited propagation. Secondary ion mass spectrometry (SIMS) mapping of elemental distributions on the surfaces of these pits suggested that the accumulation of Ni and Mo at the bottom of pits was the cause for the limited penetration depth. For this material, propagation driven by internal proton reduction was the predominant process. Lastly the high temperature corrosion of Ti-7 under both planar and creviced conditions was studied. Despite the presence of Pd, Ti-7 showed some general corrosion activity in the NaCI solution as indicated by oxide film breakdown/repassivation transients. The transient activity increased with temperature. Overall, however, these transients did not have a major degrading effect on the oxide film. The material remained passive under open circuit conditions. Ti-7 was also found not immune to crevice corrosion. For temperatures above 80 degrees C, it showed minor reactivity within the crevice. The crevice attack on Ti-7 appeared as very shallow pits with penetration depths

Book Synopsis Identification of Crevice Corrosion in ASTM Grade-12 Titanium in Simulated Rock Salt Brine at 150°C by : TM. Ahn
Download or read book Identification of Crevice Corrosion in ASTM Grade-12 Titanium in Simulated Rock Salt Brine at 150°C written by TM. Ahn and published by . This book was released on 1984 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: ASTM Grade 12- titanium (Ti-0.3Mo-0.8Ni) is a candidate corrosion resistant material for high-level nuclear waste containers which will be emplaced in mined geologic repositories such as those in rock salt. The crevice corrosion behavior of this alloy was investigated in simulated rock salt brine solutions at a temperature of 150°C. A distinct corrosion product with a range of interference colors was observed in a mechanically simulated crevice after two- to four-weeks' exposure. Low pH (~4) accelerated the reaction rate, and deaerated solutions gave less voluminous corrosion than aerated ones. Also, increasing specimen size, decreasing crevice gap, and preoxidation of the cathodic area gave more crevice attack. Higher temperatures (~250°C) do not necessarily accelerate crevice corrosion. These results are consistent with those expected from macroscopic concentration cell formation accompanied by oxygen depletion, potential drop, and acidification inside the crevice. Transmission electron microscopy (TEM) and scanning electron icroscopy (SEM) techniques were extensively utilized to identify the film formed inside the crevice at each stage of the corrosion process. In the early stage of cell formation, anatase-type titanium dioxide TiO2 was formed which acted as a barrier to further corrosion inside the crevice. Traces of titanium pentoxide (Ti3O5) were also identified. In the case of severe crevice corrosion, the corrosion product was identified as the rutile form of TiO2 which is not an effective barrier to further corrosion. Measurements of the open circuit corrosion potential at 80°C implied that there is a breakdown of the passive film as the pH of the brine falls below unity, based on the mixed potential theory. The observation of pitting inside the crevice supports the depassivation hypothesis. Accelerated hydrogen uptake was observed in the crevice region. This was caused by breakdown of the passive film or by high acidity in the crevice. Based on these observations, and pH and potential measurements inside the crevice of commercially pure titanium by other workers, a mechanism for crevice corrosion in ASTM Grade-12 titanium has been developed. It involves the initial formation of compact anatase crystals inside the crevice. As the macroscopic cell develops further, it is postulated that either the anatase form of TiO2 will transform to the lower oxide Ti3O5 or to the rutile form of TiO2, or alternatively titanium dissolves into the solution after the breakdown of the protective film and subsequent hydrolysis takes place to form the lower oxide and the rutile form of TiO2. The role of alloying elements (molybdenum and nickel) and dissolved species are discussed with respect to these postulations.
