The oxide film formed on an indium electrode immersed in a sodium borate (Na2B4O7) solution is influenced by the solution's concentration, pH, and temperature, as revealed open-circuit potential (OCP) polarization techniques. rate of growth decreases with increasing pH rising temperature. In this study, we employed Taguchi's design experiments (DOE) to minimize number experimental trials while identifying optimal conditions for reducing corrosion. primary objective was lower corrosion (CR) optimizing process parameters using "smaller better" approach signal-to-noise (S/N) ratio. This optimization based CR values derived from OCP potentiodynamic data. An L25 (5³) orthogonal array (OA) used evaluate three key factors: Na2B4O7 factor combination determined be (A1 B2 C1), corresponding concentration 0.100 ± 0.05 mol/L, 10.51 0.002, temperature 15 0.4 °C. These were identified most effective minimizing under studied conditions.
