Ultrasonic-assisted electrodeposition of Ni/diamond composite coatings and its structure and electrochemical properties.

Ni/diamond composite coatings have been synthesized by ultrasonic-assisted electrodeposition in a Ni electroplating bath containing diamond nanoparticles. The influences of current density and ultrasonic agitation on the coating composition, morphology, topography, phase structure, and electrochemical characteristics of the electrodeposits were evaluated. Ultrasonic agitation was provided using an external ultrasonic bath at a frequency of 40 kHz and acoustic power of 300 W.

Ultrasonic-assisted electrodeposition of Ni-Cu/TiN composite coating from sulphate-citrate bath: Structural and electrochemical properties.

Ni-Cu/TiN nanocomposites were electrodeposited by incorporation of TiN nanoparticles in Ni-Cu matrix from sulphate-citrate bath with additives. Ultrasonic assistance was performed in an external ultrasonic bath at ultrasonic frequency of 40 KHz and acoustic power of 300 W. The effects of current density on surface morphology, structural and electrochemical properties of Ni-Cu/TiN nanocomposites were examined.
