Characterization of pitting corrosion in aluminum films by light scattering
We report a detailed study of the morphology of pits formed by corrosion of aluminum thin films using an in-plane light scattering technique. We show that the corrosion front of the Al thin film can be treated as a quasi-two-level random rough surface. Based on an elastic diffraction theory, we are able to determine the average depth, the area, and the density of pits, as well as the fractal di...
متن کاملPitting Resistance of Pure Fe-17%Cr Alloys: Consequences for Localized Corrosion Modeling
Pitting corrosion was observed on a high purity Fe-17Cr alloy in 0.02M NaCl solution of pH 6.6 at high anodic potential (+ 550 mVISCE). Potentiostatic electrochemical noise measurements were performed, revealing the presence of a characteristic current noise below stable pitting, differing strongly from that observed 011 a series of AISI 430 type 17% Cr stainless steels, with respect to the fre...
متن کاملCorrosion Resistance of Dental Alloys
Metals and metallic alloys are unavoidable materials in everyday dental use for the making of fillings, cast cores and post systems, individual crowns, implantants’ suprastructures, dentures and orthodontic devices. They still belong to the vital materials in dentistry. Applied alloys in a mouth are exposed to the influence of chemical, biological, mechanical, thermal and electrical forces whic...
متن کاملTHE ROLE OF ALKALINE CLEANING SOLUTIONS AND CL-CONTAINING LUBRICANTS ON PITTING CORROSION IN NiTi ALLOYS
Alkaline cleaning agents are found to react with remnant manufacturing lubricants trapped in surface defects of a NiTi alloy to form Cl-based salts. These sub-surface “reservoirs” may act as nucleation sites for pitting corrosion either latent under ambient conditions, or on exposure to a limited range of high temperatures used to impart pseudoelastic properties in these alloys as part of norma...
متن کاملTarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys
Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...
