Toxic and genotoxic effects of trivalent and hexavalent chromium - A review
(2005-06-01)
During the last years, the emission of heavy metals to the environment has increased, causing a severe negative impact to the ecosystems and seriously compromising human health due to their mutagenic potential. Tri- (III) ...
Screen-printed carbon electrode modified with poly-L-histidine applied to voltammetric determination of chromium (VI)
(2006-12-01)
The present work reports the use of a screen-printed carbon electrode (SPCE) modified by poly-L-histidine film to determine chromium (VI). Stable films can be formed by direct addition of PH solution 1 % (w/v) on the ...
Electrochemical behavior of metallic chromium in chloride media
(Electrochemical Society Inc, 2000-01-01)
The electrochemical behavior of metallic chromium in aqueous solutions containing chloride ions at different pH was studied by means of open-circuit potential vs. time measurements, cyclic voltammetry and electrochemical ...
An investigation of electrolytic surface damages and electroplated crhomium effects on fatigue behavior of high strength steel
(2001-12-01)
Fatigue crack initiation occurs at the surface, although sub surface nucleation has also been reported. Localized imperfections like inclusions close to surface and surface small pits can result in crack sources. Coatings ...
Evaluation of metals in water and sediments of micro-basins in the city of Americana, São Paulo state, Brazil
(2013-05-29)
Water pollution found in major rivers in Brazil has its origin from urban sewage discharges and industrial effluent, carried out by small streams and rivers crossing cities. Therefore, studies related to hydrographic ...
EVALUATION OF HVOF SPRAYED WC-13Co-4Cr AND HARD CHROMIUM ELECTROPLATED ON STAINLESS STEEL 15-5PH FATIGUE STRENGTH
(Inegi-feup, 2017-01-01)
Fatigue failure is the result of a crack initiation and propagation as a consequence of cyclic loading. In the aeronautical industry, for components like landing gear, fatigue strength is an important parameter to be ...
