It were studied two methods of increasing the corrosion resistance of iron-base electroplates: alloying the electroplates with copper, and through the thermochemical treatment of the electroplates. It was established that alloying the iron coatings with copper conducts to changes in the surfaces morphology, physicomechanical, corrosion and electrochemical properties. The corrosion tests have shown that samples, coated with the iron-copper alloy, corrode in the NaCl solution by ~ 1.4, but in 0.05 M solution of Na2SO4 – by ~ 2 times slowly than with the iron coatings. It is determined that at the nitration of iron coating the obtained conversion layer is less porous and provides a higher corrosion resistance. This is confirmed through he fact that corrosion potential moves in positive direction with 0.815 V in comparison with the 45 steel, which wasn’t exposed to the thermal treatment, and with 0.448 V in comparison with the 45 steel, nitrided in the same conditions as the electroplate. Accordingly, the currents of anodic dissolution decrease with 3 and 4-5 orders |
