Abstract

 In this study, the pitting corrosion behaviour of Al-Nano ZrO2 NANO COMPOSITEs fabricated by Accumulative Roll bonding (ARB) process was investigated. Strips of 1050-aluminum alloy of length 250 mm, width of 40 mm, and thickness of 1 mm annealed at 623K in ambient atmosphere and analytical grade of ZrO2 powder with an average size of 40nm were used as raw materials. The Al-Nano ZrO2 composite was produced in 5 cycles. For electrochemical measurements, the square specimens of 10mm×10mm×1mm were cut, connected to copper wires and cold mounted. The open circuit potentials (OCP) of the specimens were measured after 24h immersion in the artificial seawater (3.5wt% NaCl), then CYCLIC POLARIZATION TEST were carried out at range of -0.25 / 1 v with respect to OCP and scan rate of 1mV/s. The results of CYCLIC POLARIZATION TEST indicated that when rolling cycles increase, the Eb and Eb-Erp decrease. The repassivation improved by decrease in Eb-Erp. SEM images represent the decrease and uniform distribution of pits on the surface of samples by increasing the rolling cycles.
