DEVELOPMENT OF Ni-SiC COMPOSITE COATINGS FOR CORROSION STUDIES

A.V.Seetha Girisha, Dr.K.V.Sharma

In the present work, the effect of electrochemical bath parameter like corrosion rate on physical and mechanical properties of Nickel based SiC composite coating on Mild Steel substrate was studied. Ni-SiC nano-composite coatings were prepared on a MS substrate by electro-co-deposition process using a sulphamate bath. Corrosion rate, by using a salt spray test, was measured at different experimental conditions and the results were tabulated. The experimental results showed that the corrosion rate was lowest at SiC loading of 4 gm/l, 3 A/dm2 of Current density and 45oC of bath temperature
