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 ...
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 ...
Corrosion causes in thermal power plants and ways of prevention / Uzroci korozije u termoenergetskim postrojenjima i načini prevencije
(Belgrade, Serbia : Engineering Society for Corrosion, 2009)
Corrosion damages often exert considerable influence on outages number and hence on the loss of thermal power plant availability. In order to accomplish the aim of reducing the corrosion to it's minimum and prevent main ...
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 ...
Laser cleaning of the archaeological metal sample from the Danube / Istraživanje mogućnosti primene lasera u čišćenju arheoloških metalnih predmeta
(Belgrade, Serbia : Engineering Society for Corrosion, 2018)
The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The ...
Mechanisms of hydrogen evolution on chromium / Mehanizmi izdvajanja vodonika na hromu
(Institut za rudarstvo i metalurgiju Bor, 2015)
In this work, the mechanisms of hydrogen evolution on the metal chromium in a solution of 0.1 M Na2SO4 + H2SO4, pH 1 to pH 7 were analysed. In the pH LT 3 range, hydrogen is evolved according to three different mechanisms, ...
Modified tannins for alkyd based anticorrosive coatings / Primena modifikovanih tanina u antikorozionim alkidnim premazima
(Belgrade : Engineering Society for Corrosion, 2019)
The study of the synthesis of anticorrosive inhibitors, based on chemically modified tannins, and
their use in alkyd based coatings to improve anticorrosive properties is presented in this work.
Two methods of tannin ...
Testing the protective ability of corrosion inhibitors in dilute chloride solutions / Ispitivanje zaštitne sposobnosti inhibitora korozije u razblaženim rastvorima hlorida
(Belgrade, Serbia : Engineering Society for Corrosion, 2017)
After sterilization of meat cans in a factory of meat and meat products in Serbia, occurence of corrosion on the can lids was observed. Sterilization of cans is usually performed in the presence of corrosion inhibitors. ...
Chemical corrosion of metals and alloys / Hemijska korozija metala i legura
(Belgrade, Serbia : Engineering Society for Corrosion, 2016)
In this paper, phenomena of chemical corrosion of metals and alloys in electrolyte solutions are analyzed. It is shown that iron, chromium and other metals and alloys dissolve much faster than is the corrosion rate determined ...
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 ...
