The mechanical and electrochemical properties of a low carbon steel alloy were improved with titanium (Ti) nitrides thin films. A nitriding process ensures the adhesion of the deposited thin films and provides the nitrogen source involved in the formation of the desired nitrides. A hybrid reactor was used to permit this duplex surface treatment and to avoid the oxidation of our samples. The X-ray diffraction revealed the formation of nitrided phases (TiN and Ti2N). The scanning electron microscopy showed an improvement in the adhesion of the deposited thin films with increasing negative bias voltages. The nanohardness of the duplex treated samples was found to be improved. The results obtained after the corrosion tests indicate a reduction of electrochemical activity and therefore an improvement of corrosion resistance. |
