The effect of metal surface condition on brightness and structure of metal coatings. PART I, Surface reflection of the light / Uticaj stanja površine metala na sjaj i strukturu metalnih prevlaka. I deo, Površinska refleksija svetlosti
(Belgrade, Serbia : Engineering Society for Corrosion, 2007)
Mirror brightness of metal surfaces can be associated with the high degree of mirror reflection which approaches very nearly the ideal reflectance of the same metal. The samples of steel and copper are processed by ...
The effect of current density, deoisition time and electrolytic pH value on roughness of copper coatings / Uticaj gustine struje, vremena taloženja i pH – vrednosti elektrolita na hrapavost prevlaka bakra
(Belgrade, Serbia : Engineering Society for Corrosion, 2006)
The copper coatings were electrodeposited directly onto aluminium from the bath: (CuSO4 (55 g/dm3) + CH2 NH2 - CH2OH (100g/ dm3) + (NH4)2SO4 (30 g/dm3) + Na2SO4(10H2O (75g/dm3) + Na2CO3 (3g/dm3), room temperature, j = 0.3 ...
The roughness of silver coatings electrodeposited onto aluminium / Hrapavost prevlaka srebra taloženih galvanostatskim putem na aluminijum
(Belgrade, Serbia : Engineering Society for Corrosion, 2006)
In this paper the surface roughness of silver coatings electrodeposited as final coatings onto aluminum was analyzed. The copper coating was electrodeposited as a basic coating directly onto aluminum. Afterward, nickel and ...
Direct electroplating of copper coatings onto aluminum / Neposredno elektrohemijsko taloženje prevlaka bakra na aluminijum
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
The deposition of copper coatings has been done by direct electrochemical deposition from the solution: CuSO4 (55 g/dm3) + CH2 NH2 - CH2OH (100 g/dm3) + (NH4)2SO4 (30 g/dm3) + Na2SO4*10H2O (75 g/dm3) + Na2CO3 (3 g/dm3), ...
Biomarker distributions as indicators for the depositional environment of lacustrine sediments in the Valjevo-Mionica basin (Serbia)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
In this study, the molecular composition and biomarker distribution of lacustrine sediments from Val-1 drillhole in the central zone of the western part of the Valjevo-Mionica basin were investigated at depth interval of ...
