Abstract
U radu je ispitano korozijsko ponašanje Cu kao i legura CuAl i CuZnPb u mirujućoj morskoj vodi pri temperaturama 10, 20, 30 i 40°C, dok je utjecaj gibanja elektrolita ispitan pri 20°C uz miješanje magnetskom mješalicom, brzinom miješanja od 200 o min -1 . Ispitivanja su provedena elektrokemijskim metodama kao što su mjerenje potencijala otvorenog strujog kruga u periodu od 60 minuta, metodom linearne i potenciodinamičke polarizacije. Ispitivanja su pokazala da porast temperature morske vode ima značajan utjecaj na porast gustoće korozije struje i smanjenje vrijednosti polarizacijskog otpora, dok je utjecaj na vrijednost korozijskog potencijala gotovo zanemariv. Gibanje morske vode također ima negativan utjecaj na korozijsku nestabilnost Cu i Cu legura. Analiza površine uzoraka nakon elektrokemijskih ispitivanja optičkom mikroskopijom i optičkom profilometrijom, potvrdile su rezultate elektrokemijskih ispitivanja.
Abstract (english)
In this work, the corrosion behavior of Cu, CuAl and CuZnPb alloys in still seawater was studied at temperatures of 10, 20, 30, and 40°C, while the influence of electrolyte agitation was investigated at 20°C mixing with a magnetic stirrer at a mixing speed of 200 rpm. The investigations were carried out by electrochemical methods such as measuring the open circuit potential over a period of 60 minutes, using the method of linear and potentiodynamic polarization. The tests showed that the increase in seawater temperature has a significant effect on the increase in corrosion current density and the decrease in the value of polarization resistance, while the effect on the value of corrosion potential is almost negligible. The movement of seawater also has a negative effect on the corrosion stability of Cu and Cu alloys. Analysis of the surface of the samples after the electrochemical test by optical microscopy and optical profilometry confirmed the results of the electrochemical test.
