Abstract
U radu je provedeno ispitivanje elektrokemijskog ponašanja CuAlMnZn legure u 0.5 mol dm -3 NaCl otopini različitih koncentracija (0,1, 0,5, 0,9 i 1,5 %) pri T = 20 o C i pH = 7.4, uz miješanje magnetskom miješalicom s brzinom vrtnje miješala od 150 o/min. Primijenjene su elektrokemijske tehnike kao što su mjerenje potencijala otvorenog strujnog kruga, metode linearne i potenciodinamičke polarizacije. Također je provedeno i mjerenje metodom cikličke voltametrije, u području potencijala od -1.2 V do +1.2 V s brzinom promjene potencijala od 10 mVs -1 . Povećanje koncentracije kloridih iona dovodi do negativiranja potencijala otvorenog strujnog kruga legure, povećanja gustoće korozijske struje i smanjenja vrijednosti polarizacijskog otpora. Korodirane površine elektroda nakon polarizacijskih mjerenja, ispitane su optičkim mikroskopom.
Abstract (english)
The electrochemical behavior of CuAlMnZn alloy in NaCl solution of different concentrations (0,1, 0,5, 0,9 and 1,5 %) at T = 20 o C and pH = 7.4, stirred with a magnetic stirrer with a stirrer speed of 150 rpm, was examined. Electrochemical techniques such as open circuit potential measurement, linear and potentiodynamic polarization methods have been applied. Measurements were also performed by the cyclic voltammetry method, in the potential range from -1.2 V to +1.2 V with a potential scan rate of 10 mVs -1 . Increase in concentration of chloride ions leads to a lowering open circuit potential values of alloy, increase in corrosion current density and a decrease in values of the polarization resistance. After polarization measurements, corroded electrode surfaces, were examined with an optical microscope.
