Article
Full-text available
This communication addresses corrosion behaviors of two steels employed as construction elements in underground mining, precisely mild steel st.25 (0.23 % C) and low alloyed carbon steel KP-355 (0.19 % C, 0.96 % Cr, 0.36 % Cu). Tests were carried out in representative synthetic media containing chlorides and sulphates in different ratios and variou...

The effects of different factors such as concentration (2.0÷11 vol. %) and temperature (20÷70 o C) on formations, compositions and morphologies of coatings obtained by treatment of aluminum (Al-99.5 %) surfaces in solutions containing ammonium and sodium phosphates, MoO4 2-promoting ions, buffers, softeners, inorganic activators, as well as surfact...

A comparative study concerning corrosion behaviours of two steels suggested as construction materials in mining industries have been carried out. Samples of widely used carbon steel st.25 and the new conceived, low-alloyed, steel КР-355 (0.96 % Cr, 0.36 % Cu) have been tested. The tests have been held in model media containing the main aggressive c...

Full-text available
The effect of the cold plastic deformation (0÷80 %) on the main mechanical characteristics, microstructure and the residual stresses of low-alloyed (Cr~2 %) carbon steel have been investigated applying various physical and electrochemical methods. The results revealed that with increase in the degree of deformation there was significant enhance in...

The implant materials used in medicine are made from different materials and the principle requirement to each material used is its biocompatibility. This work reports preliminary results regarding assessment of high nitrogen stainless steel (HNS) Cr18Mn12N as an implant material replacing of the common Ni containing stainless steels which are toxi...
Article
Poly(3,4-ethylenedioxythiophene) (PEDOT) films are synthesized in the presence of various anions and surfactants (perchlorate, dodecylsulfate (DDS), polysterenesulfonate (PSS) and poly(2-acrylamido-2-methyl-1-propanesulfonate (PAMPS), and polyoxyethylene-10-laurylether (PLE)) on glassy carbon electrodes. The electrocatalytical activity for acetamin...
Article
Full-text available
Electrochemical synthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) is carried out in four different polymerization solutions. Three sulfonate-based dopants, i.e. dodecylsulfonate (SDS), polysterensulfonate (PSS) and poly(acrilamidopropane-sulfonate) (PAMPS), as well as the non-ionic surfactant polyoxyethylene-10-laurylether (PLE) in combination...
