Role of Anodic Time in Pulse-Reverse Electrocodeposition of Nano-SiC Particles

This work focuses on the significance of particle's residence time in composite electrodeposition. Ni-SiC were produced using different pulse-reverse (PR) waveforms based average particle diameter (60 nm). The waveform was designed to deposit a metal thickness equivalent during cathodic pulse and strip half anodic pulse. shape modified study its effect codeposition by changing current density peaks cycle while maintaining same charge. For benchmark, samples also under direct (DC), matching average. electrodeposition done an additive-free SDS-Watts bath. ζ-potential measurements employed determine interaction between particles electrolyte. A relation established incorporation rate at electrode interface, examining. microhardness deposits studied. SiC content more than doubled PR compared DC, from 2 vol.% 5.5 even after SDS addition. increase related time, supported existing models mechanisms codeposition.
