SiC particles are known as reinforced materials used to improve the coating’s properties and performances. In this paper, Ni - SiC composite coatings were deposited by conventional electroplating from sulfate-chloride bath, and brush electroplating methods from modified chloride bath with different dispersed SiC contents. The plating conditions were investigated and the process’ parameters were defined through electrochemical technique. Scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and micro-hardness test were used to clarify the effect of SiC content on coating’s properties and performances. The hardness of brush electrodeposit reached the highest value of 525 HV when the concentration of SiC in the plating solution was 4 g/L, while the hardness of conventional electrodeposit was only 389.3 HV when the plating bath contained 20 g/L SiC. The characterized results show clear advantages of brush electroplating compared to the conventional method to form the coating with high micro-hardness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
