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.

Indentation Fracture Toughness

Chromium oxide is a promising material for applications where excellent corrosion resistance, high hardness, and high wear resistance are needed. However, its use is limited because of low fracture toughness. Improvement of fracture toughness of chromium oxide while maintaining its afore mentioned key properties is therefore of high interest. In this communication we study the possibility of increasing the toughness of pulsed electric current sintered (PECS) chromium oxide by the addition of graphene oxide (GO). The indentation fracture toughness was improved markedly with the addition of graphene oxide. Materials prepared by direct chemical homogenization had better fracture toughness. In composites with 10 vol.% GO piling of thin graphene oxide layers resulted in the formation of graphite layers between Cr2O3 and in carbide formation, which were observed to be the main reasons for the degradation of the mechanical properties. The distribution of graphene oxide was more homogeneous, when the GO amount was 0.1 vol.% and the formation of graphitic layers were avoided due to lesser amount of GO as well as ultrasonic treatment following the ball milling.
