The main objective of this work is to evaluate the %Weight loss and surface roughness of duplex coated Ti6Al4V alloy using Taguchi Optimisation Technique. In the present work, Taguchi Design is considered with four process parameters: applied load, sliding speed, sliding distance and track diameter each to be varied in four different levels. Data related to %Weight loss and surface roughness have been measured for each experimental run. The variation of output responses with process parameters were mathematically modelled by using Taguchi Optimisation Technique. Response is predicted and Signal to Noise ratio was applied to %weight loss and surface roughness. Results showed that the predicted and experimental values are good in agreement. The contribution of each process parameter is also determined by using ANOVA.
