Influence of Ph galvanic Baths on the Nickel Deposits
(Universitatea "Dunărea de Jos" din Galați, 2009)
The influence of pH on cathodic and anodic current efficiency, surface quality
and morphology of nickel deposit in the electrolyte solutions of the Watts bath type
was investigated. Cathodic current efficiency of nickel ...
Corrosion Behaviour of Tombac Used in Cult Objects Manufacturing
(Universitatea "Dunărea de Jos" din Galați, 2009)
Corrosion of metals and metallic alloys is due to their thermodynamic
instability in relation to their oxidation form. Corrosion tests performed in this work
simulate the exposure conditions in different environments of ...
