Abstract
Pulse-reverse Current (PRC) electrodeposition technology is a highly versatile and cost-effective means of controlling the films. The microstructure and grain size of high-quality Ni films deposited by PRC are studied. Regarding the exchange current density, a new parameter, “artificial exchange current density” (jA), in the PRC process is proposed. This paper derives the expression of jA and verifies its influence on the microstructure of the Ni films. Experimental results from three different baths confirmed that jA is positively correlated with grain size. This study is instructive for designing metal electrodeposition using the PRC method.
