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 ...
Corrosion testing of sa 387 gr. 91 steel
(Society for Structural Integrity and Life, Institute for Material Testing, 2017)
Corrosion behaviour of steel Sa 387 Gr. 91 is tested in solutions containing chloride and sulphate anions. These solutions simulate the conditions of marine and industrial atmosphere. The tests are carried out in a slightly ...
Influence of welding current intensity on pitting corrosion resistance in welded joint of stainless steel X5CrNi18-10 / Uticaj jačine struje zavarivanja na otpornost prema piting koroziji zavarenog spoja nerđajućeg čelika X5CrNi18-10
(Belgrade, Serbia : Engineering Society for Corrosion, 2017)
The effect of welding current on the pitting corrosion resistance in the welded joint of austenitic stainless steel X5CrNi18-10 was tested. Welding was carried out using three different current intensity (110 A, 130 A and ...
Direct synthesis of noble metal nanostructures on carbon support by hydrothermal process / Direktna sinteza nanostrukturnog plemenitog metala na ugljeničnoj osnovi pomoću hidrotermalnog procesa
(Belgrade, Serbia : Engineering Society for Corrosion, 2015)
Nanostructures of noble metals (Pt and Ag) on carbon support were prepared from fructose and solution of the Nobel metal salts (H2PtCl6 x 6H2O or AgNO3) under hydrothermal conditions. Commercial fructose (C6H12O6) acts as ...
