Original Abstract

This paper deals with corrosion behaviour of AlCu4Mg1 alloy in the aqueous solution inclusive 0.07 mol of urea + 0.03 mol of sodium chloride dissolved in the water. Corrosion tests were performed as a modified OECD technique. The samples were placed into the small testing cells for provision no interaction of the samples. There were 30 ml of corrosion solution on the bottom of each cell and the samples were hung up above the surface. Testing mode was cyclical (8 hrs 35 C, 16 hrs 23 C – 1 cycle). The experiments were carried out with increasing exposition time (1, 5, 10, 20, 31 and 42 cycles). The weight losses were evaluated and the statistic analysis was performed. First the Dixon test extreme deviations (maximal and minimal values) and then the corrosion rate [g m-2 d-1] were calculated from the weight losses.
