Study the effect of cold rolling of aluminum-magnesium (5083)‎ alloys on the erosion-corrosion test at the impact angles (30°, 90°)‎ in river water

الملخص EN

The present work investigates the effects of cold rolling on the erosion- corrosion rate of (Al-Mg).

The alloys specimens which were used for the marine applications were cold rolled at different reductions (2.5, 5, 7.5%), then tested for erosion- corrosion using dynamic rig at different exposure time (0-15 h).

to measure the erosion–corrosion rate at impact angles (30º, 90º) .

The results showed that the heat treatment of alloys (5083) didn’t improve the erosion- corrosion resistance; this was noticed in the homogenized specimens.

Erosion/corrosion resistance at impact angles (30º, 90º) was found good at two impact angles, While erosion/corrosion resistance for (5083) alloys at impact angle 90º was found higher than impact angle 30º, The specimens of the rolled alloys (2.5, 5, 7.5%) reductions showed erosion/corrosion resistance higher than before and after homogenizations process at both impact angles of (30º & 90º) respectively.

The percentage error that obtained from experimental and theoretical at impact angles 30º & 90° were 25 % and 30% respectively.
