Abstract : Coatings are one of the rising techniques to stop degradation of metals’ surface from corrosive pitting and wear. Electroless Ni-P coatings were developed and successfully deposited over Copper substrate. The coating was varied by varying the concentration of the metal source, Nickel Sulphate and the reducing agent, Sodium Hypophosphite. The corrosion rates of all the coatings were measured using Tafel Tests. Taguchi modelling was done with the help of L9 orthogonal arrays with corrosion rate as the response parameter. The optimized sample was obtained based on the Signal to Noise ratio of individual levels of the coatings. The level 1 and level 3 of the above mentioned factors were the optimized parameters. The optimized sample was characterized using Energy-Dispersive X-Ray Analysis, Scanning Electron Microscopy. Energy-Dispersive X-Ray Analysis showed the Ni-P coating was a medium Ni-P coating.
