Abstract:
Corrosion resistance of an orthodontic wire made of Gold 18K alloy immersed in artificial saliva in the absence and presence of 500 ppm of Éclairschocolate candy has been investigated by potentiodynamic polarization study and electrochemical impedance spectra (EIS). It is observed that corrosion resistance of Gold 18K alloy immersed in artificial saliva in the presence of 500 ppm of Éclairs chocolate candy increases. Hence it is concluded that people clipped with orthodontic wire made of Gold 18K alloy need not worry about taking Éclairs chocolate candy orally. When Gold 18K alloy is immersed in artificial saliva in the presence of 500 ppm of Éclairs chocolate candy, Linear Polarisation Resistance (LPR) value increases from 4844947 Ohmcm2 to 35700904 Ohmcm2 ; corrosion current decreases from 7.726x10-9A/cm2 to 1.350x109A/cm2 ; charge transfer resistance value(Rt) increases from 172100 Ohmcm2 to 398800 Ohmcm2 ; impedance value increases from 5.445 to 5.975; double layer capacitance decreases from 2.963x10-11F/cm2 to 1.1279x10-11F/cm2 , and phase angle increases from 44.68° to 48.23°.
