Abstract
Wear resistance of electrodeposited tertiary alumina/carbon nanotube/nanodiamond nanocomposite using pulsed current has been studied in Ni–W binary alloy matrix. Electroplating process was performed in citrate based Ni–W bath, and the nanostructure of obtained compound layer was examined by AFM. The effects of process variables, i.e. tungsten concentration in electrolyte, treatment time, frequency and duty cycle, were experimentally studied. Statistical methods were used in order to provide the minimised wear rate. Finally, the contribution percentage of different effective factors was calculated and confirmation run revealed the validity of obtained results. Nanocomposite layers with higher density of nanoparticles will show better tribological properties.
