The Effect of Ultrasound Treatment on Physicochemical and Tribological Properties of Electrolytic Cu-Sn-TiO2Coatings

In this work, Cu-Sn-TiO(2)composite coatings have been deposited from an oxalic acid electrolyte additionally containing 4 g/dm(3)TiO(2). Using energy-dispersive X-ray spectroscopy and X-ray fluorescence analysis, the influence of ultrasonic treatment and current load on the inclusion and distribution of the dispersed TiO(2)phase in the Cu-Sn metal matrix has been established. Scanning electron microscopy confirmed that ultrasound treatment leads to the formation of more uniform Cu-Sn-TiO(2)coatings. It has been shown that an increase in the cathodic current density from 0.5 to 1.5 A/dm(2)leads to the formation of coatings with higher TiO(2)content. The effect of ultrasonic action and current load on the microhardness, tribological properties, and corrosion resistance of the formed Cu-Sn-TiO(2)composite coatings have been studied.
