Economizer water-wall damages initiated by feedwater impurities
(Association of Chemical Engineers of Serbia, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Microstructure and corrosion behaviour of Zn-Co alloys deposited from three different plating baths / Mikrostruktura i koroziono ponašanje Zn-Co legura taloženih iz sulfatnog i hloridnih rastvora
(Serbian Chemical Society, 2011)
The effects of plating baths of different composition on the micro- structure and corrosion stability of Zn-Co alloy coatings were studied. Zn-Co alloys with the same Co content were deposited from chloride plating baths ...
Ternary Zn-Ni-Co alloy: anomalous codeposition and corrosion stability
(Serbian Chemical Society, 2015)
Electrochemically deposited Zn-Ni-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy for the determination of the chemical composition, atomic force microscopy for surface ...
Influence of chloride ions on the open circuit potentials of chromium in deaerated sulfuric acid solutions / Uticaj hloridnih jona na potencijal otvorenog kola hroma u deaerisanim rastvorima sumporne kiseline
(Serbian Chemical Society, 2006)
Open circuit potential measurements and cyclic voltammetry of chromium in deaerated aqueous H2SO4 solution of pH 1 without and containing NaCl in the concentration range 0.5 - 4 M revealed that chromium exhibits two stable ...
Structural effects of metallic chromium on its electrochemical behavior / Uticaj strukture metalnog hroma na njegovo elektrohemijsko ponašanje
(Serbian Chemical Society, 2007)
Chromium dissolution in aqueous sulfuric acid solution of pH 1 was studied electrochemically on chromium electrodes with different crystallographic structures. A slow potentiodynamic method was used for the electrochemical ...
