Abstract
In this study, coatings were produced at different tungsten (W) sources concentrations in plating baths by the electrodeposition method. The concentration of sodium tungstate was 10, 20, 40 g/L, and the pulse current (PC) method was preferred for prepared of the coatings. The surface morphology, coating thickness, phase analysis of the coatings were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) methods. The hardness of coatings were measured by the microhardness (Vickers) method. Finally, the coatings were subject to wear tests to determine the coefficient of friction and wear rate. As a result of the studies, it was seen that the coating obtained from the sodium tungstate concentration of 20 g/L had the highest hardness with 859 HV. Wear tests also showed that the lowest friction coefficient and wear rate were seen for coating produced at this concentration.
