The effect of ultrasonic power on high temperature wear and corrosion resistance for Ni based alloy composite coatings
TiO2-reinforced Ni-W co-depositions are successfully produced by ultrasonic-assisted pulse electrodeposition. The effect of ultrasonic powers and concentration of TiO2 on the surface morphology, surface roughness, nano-mechanical, anti-corrosion, high-temperature wear, and friction behavior of the Ni-W co-depositions were systematically investigated. The experimental results indicate that (1) there is an optimal incorporating amount (about 20 g L?1) of TiO2 in the plating bath and ultrasonic power (50 W) for achieving the highest high-temperature wear, corrosion resistance and excellent nanomechanical properties (hardness of ?8 GPa and elastic modulus of ?209 GPa), maximum TiO2 incorporation rate (24.4 wt% TiO2); (2) the composite coating refined the microstructure and reduced crystallite size of the coatings, and obtained dense microstructure. TiO2-reinforced Ni-W co-deposition produced by optimal conditions open up new avenues in alternative to hard chromium and is expected to be widely applied in defense industry, automobile and electronic systems.
