Analysis of variation in electrochemical bath parameters on the properties of Ni-SiC nanocomposite coatings using Taguchi technique

摘要

In the present work, the effect of electrochemical bath parameters such as bath temperature, bath loading and current density on physical and mechanical properties of Nickel based SiC composite coating on Mild Steel substrate was studied using Taguchi technique. Ni-SiC nano-composite coatings were prepared on a MS substrate by electro-co-deposition process using a sulphamate bath. The SiC loading, current density and bath temperature were varied and the electrochemical bath parameters were measured. The main effects for each of the parameters for all the co-deposition conditions were plotted using a statistical software. The Experimental results showed that, the electrochemical bath parameters of the co-deposited coating were maximum for a value of 4 gm/l of SiC loading, 3 A/dm~2 of Current density and 55℃ of bath temperature.
