The localised corrosion resistance of 316L SS metallic implant due to H3PO4
treatment is being studied through electrochemical study involving cyclic polarisation experiment.
Buffer solutions (pH 3-9) were prepared by 0.04 M H3PO4
, 0.04 M CH3COOH, 0.04 M boric acid and the pH was adjusted with 0.2 mol L-1 NaOH solution.
After 30 min, 50 ml of deionized water, 3 ml of concentrated H3PO4
and 0.5 ml of 1% defenilamina (Barium diphenylamine sulphonate, 0.16 %) indicator were added.
A silica gel was prepared by hydrolysis and polycondensation of TEOS assisted by the dropwise addition of H3PO4
with stirring at room temperature overnight, in which the molar ratio of TEOS : H2O : H3 PO4 was 1: 11: 0.02.
