In this study we consider copper sample as a substrate under which the Electroless Ni-W-P coatings were established and successfully deposited. The three factor was taken into consideration, i.e. concentration of the Nickel Sulphate, Sodium Hypophosphite and Sodium Tungstate Dihydrate. Central Composite Design modelling was done with the help of total 20 runs that were conducted in the design, with mass deposition per unit area as the response parameter. The optimized sample was evaluated from the Design of Experiments based on Central Composite design. From where we examined the individual levels of the coatings, ANOVA, Examination of Normal Plot of Residual, Predicted and Actual plot and Second order 3-D and Contour plot showing interaction for Response Surface Mass Deposition per Unit Area.It was found that the optimized as-coated value for mass deposition per unit area has the significant process parameters, the value is linear in nature and it has highest response which is of 134.055×10-4 gm/cm2.
