RESEARCH ON THE CORROSION BEHAVIOR OF ZINC COATING BY MEASUREMENT OF POLARIZATION RESISTANCE

Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1

Abstract

Measurement of polarization resistance of micro-alloyed zinc layers followed corrosion products characterization and corrosion behavior of the default layers analyzed. We have studied microalloyed zinc coatings with different percentages of nickel, tin, bismuth, lead, cadmium, exposed to a corrosive environment with 3% NaCl at room temperature. For experimental determinations was applied  electrochemical method. A calomel saturated electrode was used as reference electrode and a platinum wire electrode as an auxiliary one. Analyzing the variation of polarization resistance for each sample, we can observe how initially the sample surface becomes active, which causes a decrease in polarization resistance followed in time by the formation of a layer of corrosion products which will cause a variation of polarization resistance.
