    Increasing Surface Coating Quality Using New Generation Current Waveforms
    (Ieee-Inst Electrical Electronics Engineers Inc, 2020) Muhurcu, Gulcin; Kulekci, Mustafa Kemal
    In this study, a novel current generator system was designed that can convert the basic signals used in engineering field into electrical current waves. The current generator system was realized by using Buck Converter and H-Bridge, which are Power Electronics circuit topologies. In order to produce the predicted current waveforms, the Artificial Neural Network (ANN), as a nonlinear control algorithm, has been adapted to the hybrid Power Electronics system. Then, Electrodeposition based coating experiments were carried out using the new generation current generator system. Copper (Cu) was used as a cathode and Nickel (Ni) as an anode in the coating process. Coating experiments were carried out for constant maximum current (Imax) conditions. The experiments were repeated with 3 different frequencies for each coating current wave. After coating, the surface morphology and sharp edge coating success of the covered areas were examined and the results were discussed by comparing to the DC's, PC's and PRC's.
