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 ...
Hydroxyapatite coatings on TiO2 nanotubes / Prevlake hidroksiapatita na nanotubama oksida titana
(Belgrade, Serbia : Engineering Society for Corrosion, 2010)
The aim of this work was to obtain nanotubular TiO2 layer by anodization of titanium substrate, and to prepare hydroxyapatite (HAP) coatings by electrophoretic deposition over nanotubular TiO2 layer. The presence of fluoride ...
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. ...
Determination of the weld metal corrosion rate using electrochemical techniques / Određivanje brzine korozije metala šava u zavarenom spoju pomoću elektrohemijskih tehnika
(Belgrade, Serbia : Engineering Society for Corrosion, 2015)
To determine corrosion rate of the base metal and weld metal were applied electrochemical techniques: linear polarization resistance, linear sweep voltammetry and electrochemical impedance spectroscopy. The samples were ...
The resistance to general corrosion of series of zinc-aluminum alloys modified with silicon and strontiumloys modified with silicon and strontium / Otpornost na opštu koroziju serije legura cink-aluminijum koje su modifikovane silicijumom i stroncijumom
(Belgrade : Engineering Society for Corrosion, 2019)
The resistance to corrosion of the series of zinc-aluminum casting alloys modified with silicon and
strontium was studied in a sodium chloride solution. It was shown that general corrosion was the
main form of corrosion ...
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 ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Belgrade, Serbia : Engineering Society for Corrosion, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
