Abstract
U radu su prikazani rezultati ispitivanja korozijskog ponašanja CuAlNi legure (Al 10,4 %, Ni 4,1 %) u 0,5 mol dm -3 H 2 SO 4 otopini, pri temperaturama od 20 i 40 °C i brzinama miješanja elektrolita magnetskim miješalom od 150 i 450 o min -1 . Ispitivanja su provedena elektrokemijskim metodama: mjerenjem potencijala otvorenog strujnog kruga, metodom linearne polarizacije i potenciodinamičkom polarizacijskom metodom. Rezultati mjerenja pokazali su negativan utjecaj povišenja temperature i brzine miješanja elektrolita koji dovode do porasta gustoće korozijske struje i do smanjenja vrijednosti polarizacijskog otpora. Nakon polarizacijskih ispitivanja površine elektroda snimljene su optičkim mikroskopom. Snimke površine elektroda optičkim mikroskopom pokazale su prisutnost interkristalne korozije na površini legure.
Abstract (english)
The results of the investigation of corrosion behavior of CuAlNI alloy (Al 10,4 wt. %, Ni 4,1 wt.%) in 0,5 mol dm -3 H 2 SO 4 solution, on temperatures of 20 and 40 °C and stirring with a magnetic stirrer with rates of 150 and 450 o min -1 , was presented. Investigations were performed by electrochemical methods: open circuit potential measurements, linear polarization method and potentiodynamic polarization method. The results of the measurements have shown negative impact of electrolyte temperature and stirring rate which is manifested by increase in corrosion current density and decrease in polarization resistance values. After polarization measurements, electrode surface was examined by light microscope. Images of electrode surfaces, obtained by light microscope, have shown the occurrence of intergranular corrosion on the alloy surface.
