| Sumario: | This paper presents an experimental study of roughness characteristics of electroless Ni-P coatings and optimization of coating process parameters based on L27 Taguchi orthogonal design. Experiments are carried out by utilizing the combination of three process parameters, viz., bath temperature, concentration of nickel source solution and concentration of reducing agent. It is observed that concentration of nickel source solution has got the most significant influence in controlling roughness characteristics of electroless Ni-P coating. The optimum combination of process parameters for minimum roughness is obtained from the analysis. The surface morphology and composition of coatings are also studied with the help of scanning electron microscopy, energy dispersed X-ray analysis and X-ray diffraction analysis. |
