Application of the Composite Hardness Models in the Analysis of Mechanical Characteristics of Electrolytically Deposited Copper Coatings: The Effect of the Type of Substrate
(Metals, 2021)
The mechanical characteristics of electrochemically deposited copper coatings have been examined by application of two hardness composite models: the Chicot-Lesage (C-L) and the Cheng-Gao (C-G) models. The 10, 20, 40 and ...
Life cycle assessment of wood chips supply chain in Serbia
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Two most common systems of forest biomass supply chains in Serbia are evaluated by using the Life Cycle Assessment (LCA) approach: 'cut-to-length' system with penduculate oak (CLO) on flat terrains with a tractor equipage, ...
Comparative study of cu(2+) adsorption on a zeolite, a clay and a diatomite from Serbia
(Applied Clay Science, 2009)
The adsorption of a zeolite, clay and diatomite from Serbia toward aqueous Cu2+ ions was studied, at different pH. The adsorbents were characterized with respect to phase composition, specific surface area and point of ...
Properties of quenched LiFePO4/C powder obtained via cellulose matrix-assisted method
(Powder Technology, 2013)
In this study, nanocrystalline LiFePO4/C composite powder has been synthesized via a cellulose matrix-assisted method. In an experiment conducted under extreme conditions involving rapid heating, short high-temperature ...
The influence of the surface nanostructured modification on the corrosion resistance of the ultrafine-grained Ti-13Nb-13Zr alloy in artificial saliva
(Elsevier, Amsterdam, 2019)
On the surface of the ultrafine-grained Ti-13Nb-13Zr alloy and the coarse-grained Ti-13Nb-13Zr alloy nanotubular oxide layers were formed by electrochemical anodization in the 1 M H3PO4 + NaF electrolyte in order to evaluate ...
Experimental study of insulating properties and behaviour of thermal barrier coating systems in thermo cyclic conditions
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to improve the resistance of turbo jet engine parts exposed to high temperatures and overheating and sudden changes in temperature. For this purpose, three thermal barrier coating (TBC) systems ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solution. Chemical composition, phase composition and morphology effects
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work the hydrogen evolution reaction (HER) onto Ni-Sn alloy coatings deposited at different current densities from the bath containing 0.1 M Sn2+ and 0.1 M Ni2+ ions in the pyrophosphate-glycine solution, was ...
Morphologies of electrochemically formed copper powder particles and their dependence on the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Copper powder particles formed by electrolysis under different quantities of evolved hydrogen were analyzed using the scanning electron microscopy (SEM) technique. It was found that the structure of the powder particles ...
