The electrode used is Platine (Pt) as the counter electrode, AgCl as the reference electrode and Tungsten Carbide (WC) as the working electrode. The variations of current used are 4 mA, 5 mA, and 6 mA. The surface morphology of composites was characterized by using Scanning Electron Microscopy (SEM). The results showed that the increase of current the layers surface morphology would be more smooth.</p> <p><strong>K</strong><strong>e</strong><strong>ywords: </strong>composite layer, electrodeposition, current, morphology</p&gt;}, journal={PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL)}, author={Oktaviani, Yani and Budi, Esmar and Sugihartono, Iwan}, year={2018}, month={Oct.}, pages={SNF2018-PA} }
