This study investigated the synthesis of Ag-SnO2-ZnO by powder metallurgy methods and their subsequent electrical contact behavior. The pieces were prepared ball milling hot pressing. arc erosion behavior material was evaluated using homemade equipment. microstructure phase evolution materials through X-ray diffraction, energy-dispersive spectroscopy scanning electron microscopy. results showed that, although mass loss composite (9.08 mg) during test higher than that commercial Ag-CdO (1.42...
The deterioration of reinforced concrete structures in marine environments presents multiple problems due to the premature degradation steel. This work aimed study corrosion A630-420H steel when exposed a 0.5 M NaCl solution. Although this carbon is most widely used material for Chile, there limited research on its resistance contact with saline solutions. electrochemical reactions and their roles rate were studied using linear sweep voltammetry, weight loss, scanning electron microscopy,...
The effect of NaCl on the leaching white metal from a Teniente Converter was investigated in NaCl-H2SO4 media under environmental conditions. copper dissolution studied using ferric ions range 1–10 g/L, 30–210 and sulfuric acid 10–50 g/L. test without produced 55%; through addition NaCl, increased to nearly 90%. not significant range, as excess simply iron precipitation. positive seems be related action chloro-complex oxidizing agents relation Cu+2/Cu+ couple. A simplified two-stage...
Abstract Antuco (37.4°S, 71.4°W; Chile) is a dominantly basaltic stratovolcano whose original ~ 3300 m altitude main cone experienced catastrophic sector collapse at 7.1 cal ka BP, producing volcanic debris avalanche deposit (VDAD) with hummocky surface and 6.4 km 3 of volume. We carried out geological studies its deposit, which was distributed to the W displays longitudinal facies transformation from edifice’s megablocks block mixed in distal areas (up 25 scar). Our observations support...
In this study, weak acid in the curing and leaching stages of copper ore was incorporated, we analyzed its effect on dissolution final impurities. The corresponds to a wastewater effluent from sulfuric plants produced gas treatment smelting processes. This is basically water with high acidity (pH-value low at 1), which contains several toxic elements some valuable metals. results indicated that there no positive or negative incorporation stage, while case stage favored. Toxicity...
The increase in longevity worldwide has intensified the use of different types prostheses for human body, such as those used dental work well hip and knee replacements. Currently, Ti-6Al-4V is widely a joint implant due to its good mechanical properties durability. However, studies have revealed that this alloy can release metal ions or particles harmful health. mechanisms are not understood yet may involve wear and/or corrosion. Therefore, work, commercial pure titanium were investigated...
