The study was carried out in order to evaluate the effect of the pulsed electric current (PEC) treatment on the corrosion as well as on static strength of Polish reinforcing steel. As-received St3SX was used for investigations. Two kinds of specimens were manufactured by turning from 20 mm diameter re-bars: cylinders of 10 mm diameter and 28 mm length for corrosion tests and standard cylindrical specimens of 6 mm diameter and 30 mm length for static tension tests. Corrosion tests was performed according to the ASTM B117-97 standard. As-received steel tensile specimens and the specimens after PEC treatment were tested using a servo-hydraulic universal testing machine at the strain rate of 10-2 s-1.

The high temperature corrosion behavior of thermal barrier coating (TBC) systemconsisting of IN-738 LC superalloy substrate, air plasma sprayed Ni24.5Cr6Al0.4Y (wt%)bond coat and air plasma sprayed ZrO2-20 wt% ceria-3.6 wt% yttria (CYSZ) ceramic coatwere characterized. The upper surfaces of CYSZ covered with 30 mg/cm2 , mixed 45 wt%Na2SO4-55 wt% V2O5 salt were exposed at different temperatures from 800 to 1000 oC andinteraction times from 1 up to 8 h. The upper surface plan view of the coatings wereidentified for topography, roughness, chemical composition, phases and reaction productsusing scanning electron microscopy, energy dispersive spectroscopy, talysurf, and X-raydiffraction. XRD analyses of the plasma sprayed coatings after hot corrosion confirmed thephase transformation of nontransformable tetragonal (t') into monoclinic phase, presence ofYVO4 and CeVO4 products. Analysis of the hot corrosion CYSZ coating confirmed theformation of high volume fraction of YVO4, with low volume fractions of CeOV4 and CeO2.The formation of these compounds were combined with formation of monoclinic phase (m)from transformation of nontransformable tetragonal phase (t').
