Corrosion resistance of iron can be drastically improved by addition of passivating alloying elements. A supersaturated solid solution of Fe-25at%Sn was produced by mechanical alloying of commercially pure iron and tin powders for 24 hours using a planetary ball mill. Electrochemical measurements were performed on cold compacted unsintered specimens.. XRD investigation on produced alloy showed ...

The current oscillatory behavior of epoxy-coated low carbon steel at anodic polarization was investigated in 3,5 % and 0,5 % solutions of NaCl. It was established, that the coated steel may show current oscillations at potentiostatic anodic polarization. The oscillations are of different type, period and amplitude and are more clearly expressed in 0,5 % solution. The presented results might be ...

Silica phases were precipitated on aluminum surface by potentiostatic plasma electrolysis technique. Aqueous sodium silicate solutions with different concentrations were used for this purpose. SEM, EDS, XRD, surface profiles and polarization curves were used to study coatings properties. The results showed that the growth of the silica containing phases on aluminum surface was promoted by incre...
