Machine parts are exposed to various effects that cause damage to material surfaces such as corrosion and wear. There are various and effective methods to protect material surfaces from these harmful effects. Electrochemical coating is one of the most preferred methods. In this study, the main structure of the Ni- B alloy was supported by titanium carbide (TiC) reinforcement particles and coated with electrochemical deposition method on AISI 304 quality stainless steel, which is highly preferred in the industry. The corrosion resistance of these obtained coatings was analyzed by electrochemical impedance spectroscopy (EIS) method. In addition to the corrosion resistance of the stainless steel substrate, pure nickel and Ni-B alloy coatings were produced and the corrosion resistance was investigated for comparison purposes. According to the results obtained, it has been determined that the Nyquist curves of Ni-B/TiC nanocomposite coatings are much more inclusive and broader than stainless steel, pure nickel and Ni-B alloys. At the same time, the phase angle values of the nanocomposite coatings in the Bode plot were also obtained much higher. According to the corrosion resistance values calculated by the equivalent circuit fitting process of the Nyquist curves, the nano-composite sample with 12 g/l TiC bath particle content exhibited the best corrosion resistance. The resistance value of this sample was ~280%, ~235% and ~307% higher than stainless steel, pure nickel, and Ni-B alloy, respectively. According to these results, it was understood that reinforcing the Ni-B alloy with TiC is extremely effective in terms of corrosion protection.
