چکیده
|
The purpose of this study was to investigate the effect of juglans regia extract concentration on the corrosion behavior of ni-cr dental alloy in artificial saliva (as) using potentiodynamic polarization (pdp), impedance spectroscopy (eis) and their surfaces were analyzed by optical microscopy (om). the presence of juglans regia extract in artificial saliva had a significant influence on the corrosion rate, the icorr value increased and linear polarization resistance (lpr) decreased in artificial saliva (as) medium, but in the presence of juglans regia extract the corrosion resistance of this alloy improved. impedance measurements confirm the anti-corrosion ability by adding the extracted plant and this is correlated to the enlargement of capacitive loops. the optical microscopic studies show the formation of a film on ni-cr dental alloy surface in the presence of the plant extract.
