Catalytic effect of sulphuric acid in the process of deposition of chromium coatings / Katalitički uticaj sumporne kiseline u procesu taloženja prevlaka hroma
(Belgrade, Serbia : Engineering Society for Corrosion, 2011)
This paper analyzes the catalytic effect of sulphuric acid on current efficiency, the coating thickness and the rate of deposition of electrochemical chromium coatings. According to the properties of chrome, there are three ...
Comparison of morphology of powder particles obtained by the constant and periodically changing regimes of electrolysis / Poređenje morfologije čestica praha dobijenih konstantnim i periodično promenljivim režimima elektrolize
(Belgrade, Serbia : Engineering Society for Corrosion, 2011)
Morphologies of copper powder particles obtained by both potentiostatic and pulsating overpotential (PO) regimes of electrolysis were analyzed using the technique of scanning electron microscopy (SEM). The parameters of ...
