【 摘 要 】

The effects of concentration of Sodium Dodecyl Sulfate (C12H25NaSO4) as surfactant on structure and hardness of electrodeposited Ni-TiAlN composite coating has been investigated. The composites were deposited at fixed current of 3 mA, 12 V for 15 minutes. The electrolyte consists of 0.49 mol/l H3BO3, 0.17 M NiCl26H2O, 0.38 M NiSO46H2O, 2 gr/lit AlN and 2 gr/lit TiN. The concentration of Sodium Dodecyl Sulfate (SDS) was varied into 0.2, 0.4 and 0.6 gr/lit. The electrodes used were Pt wire as counter electrode, silver (Ag) wire as reference electrode and tungsten carbide (WC) rod as working electrode. The surface morphology and composition of composites were characterized by using Scanning Electron Microscopy (SEM) dan Energy Dispersive Spectroscopy (EDS), respectively. The crystal structure of comosites was characterized by using X-Ray Diffraction (XRD) and the hardness was tested by using hardness Vickers tester. The results showed that a fewer aglomeration was formed on the composite surface for SDS concentration of 0.4 gr/lit. However, the increase of SDS concentration lead to the decrease of crystal size and increase the hardness of composite.
