Simulation and Rendering of Pitting Corrosion
Proceedings of the 2014 Indian Conference on Computer Vision Graphics and Image Processing, 2014Simulation and rendering of material weathering is of great interest in computer graphics as it facilitates modeling of realistic objects in virtual scenes. We present a physio-chemically based methodology to model pitting corrosion. Our simulation has two components. The first models pit nucleation on the surface of the object.

The breakdown of native and anodically grown oxide films on Ti electrodes is investigated by scanning electrochemical microscopy (SECM), video microscopy, transmission electron microscopy, and voltammetry. SECM is used to demonstrated that the oxidation of Br[sup [minus]] on Ti occurs at microscopic surface sites (10 to 50 [mu]m diam, 30 sites/cm[sup 2]

Abstract Microscopic observations have been made in situ on the pitting corrosion of polycrystalline and single crystal Ni, at a passive potential, in 1N H2SO4 solution containing Cl−. Corrosion pits were observed to nucleate at scratches and grain boundaries.

The pitting corrosion of copper
Journal AWWA, 1994To solve or prevent copper pitting problems, it is first necessary to achieve a clearer understanding of copper corrosion theory, parts of which are currently not supported by practical experience.Some current theories of copper pitting are contradicted by practical experience.

This review describes the experiments performed during the last few decades which enhance knowledge of the pitting of aluminum. Specifically, metastable and stable pits, pit chemistry and the effect of intermetallics on pitting are discussed. The properties of metastable alloys and inhibition of Al are also discussed.

AbstractCorrosion of metals and alloys by pitting constitutes one of the very major failure mechanisms. Pits cause failure through perforation and engender stress corrosion cracks. Pitting is a failure mode common to very many metals. It is generally associated with particular anions in solution, notably the chloride ion. The origin of pitting is small.

The initiation of pitting corrosion at MnS inclusions
Corrosion Science, 1993Abstract The dissolution of MnS inclusions in stainless steel exposed in 0.5 M NaCl + 0.5 M H 2 SO 4 + 0.08% H 2 O 2 at the free corrosion potential for 10 s has been studied using simultaneous Auger/EDX analysis and imaging and electron microscopy. Inclusions at different stages of dissolution have been examined.
