Summary: | In this study polypyrrole was coated on the lead silver alloy (0·5 wt-%) using electrochemical synthesis. The performance of the coating on the lead alloy corrosion behaviour in a severe corrosive electrolyte has been evaluated. Also, the morphology of polypyrrole coating was studied utilising scanning electron microscopy (SEM). The results show that the protective layer of polypyrrole decreases the corrosion rate of the anodes by about 30% for the optimum coating condition.
Dans cette étude, on a recouvert l'alliage de plomb et argent (0·5% en poids) avec du polypyrrole en utilisant la synthèse électrochimique. On a évalué le rendement du revêtement sur le comportement à la corrosion de l'alliage de plomb dans l'électrolyte sévèrement corrosif. On a également étudié la morphologie du revêtement de polypyrrole en utilisant le microscopie électronique à balayage (SEM). Les résultats montrent que la couche protectrice de polypyrrole diminue la vitesse de corrosion des anodes par environ 30% en condition optimale du revêtement. |
