COATINGS FOR CORROSION PROTECTIONS OF STEEL CARBON OBTAINED THROUGH IMPULSE ELECTRICAL DISCHARGES

The work entitled “Coatings for corrosion protections of steel carbon obtained through impulse electrical discharges” presents the research done by the authors in regards with obtaining some superficial metallic layers, on parts made of carbon steel OL 37 brand, with the help of some electrodes from a corrosion resistant material (Cu). The corrosion resistance of the experimental attained layers was obtained with the polarization curves method. The superficial layers subjected to electrochemical corrosion where analyzed through optical metallographic microscopy, using the computers QX3 Intel Play microscope. The investigations made reflected an improvement of the superficial layers quality in regard to thermodynamics corrosion probability.
