Abstract
In the present work, the Taguchi method, from the design of experiment (DOE) has been used to optimize the dip testing method to test the corrosion resistance of bio degradable materials such as PLA (Polylactic acid)and PCL (Polycaprolactone). A L9 (9) orthogonal array of Taguchi design was used, which involves nine experiments for three parameters (pH, sample, temperature) with three levels was used. Corrosion resistance in various pH change of HCL solution was evaluated by dip tests at various temperatures. Analysis of variance (ANOVA) is performed on the obtained measured data and S/N (signal to noise) ratios. The lower the better response variable was selected to obtain the optimum conditions. The optimum conditions providing the lowest weight change potential were estimated. The optimum conditions provided the lowest weight change potential. As a result, the optimum process parameters were determined. The conditions have been identified which achieve less corrosion. As a result of Taguchi analysis in this study, the factor with the most influencing parameter on the corrosion resistance is to be known to show most significant effect. The percentage contributions of pH, sample and temperature to the corrosion rate are to be seen respectively. Consequently, the Taguchi method was found to be the best promising technique to obtain the optimum conditions for such studies. Moreover, the experimental results obtained confirm the adequacy and effectiveness of this current approach.
