In this research work, a study on the coefficient of friction observed in samples made from Ti6Al4V titanium alloy textured with different types of patterns was made. Analysis of Variance (ANOVA) based on design of experiments was done to understand the contribution of type of pattern, laser power and number of passes used for texturing in affecting the coefficient of friction. The analysis indicated that the samples textured with hatch pattern produced minimum coefficient of friction while grid pattern produced maximum coefficient of friction. Along with hatch pattern single pass and 5W power setting in the laser engraving machine produced the optimum condition. The interaction between the pattern type and number of passes also contributes for the variations in the coefficient of friction.
