Ekstrak Daun Jambu Bol (Syzygium Malaccense) sebagai Inhibitor Korosi pada Kawat Ortodontik

Abstract

of the maximum corrosion rate and inhibition efficiency was in samples with a concentration of 10 g/L and 48 hours of immersion time, which was 1.19 mils per year (mpy), and the inhibition efficiency was 91.71%. Morphology to observe the surface using an optical microscope and determine the formed phase using X-Ray Diffraction (XRD). The longer the immersion of the sample with the inhibitor, the better the adsorbed inhibitor and the lower the corrosion rate. An increasing concentration will result in a smaller corrosion rate if the inhibitor concentration is given correctly.
