In the present study, the effect of temperature during electrodeposition of Ni-TiN/Si3N4 and Ni-TiAlN/Si3N4 composite coatings have been studied. The electrodeposition process was carried out for 15 minutes with a current of 5 mA and three electrodes. Pt wire as the counter electrode, AgCl as the reference electrode and tungsten carbide (WC) as the working electrode. The electrolyte solution used consisted of 0,17 M NiCl2.6H2O, 0,38 M Ni2SO4.6H2O, 6 g/L TiN, 6 g/L AlN, 0,6 g/L Si3N4, 40 g/L H3BO3 and 0,6 g/L Sodium Dodecyl Sulfate (SDS). In this stydy, the temperature variations used were 35°C, 40°C and 45°C. The samples were characterized by using SEM, EDS, XRD and hardness test. The results and discussion were presented.
