العوامل المؤثرة في السلوك التآكلي لخليطة ألمنيوم صناعية

Abstract EN

This study deals with effects of corrosive solution temperature and time of simple immersion in the solution on the corrosion behavior of aluminum alloy used in the manufacture of food machinery parts using simple immersion method in acidic solution (3%HCl-5%HCl by volume) at different temperatures (30-40-50-60-70-80)oC.

The weight loss method is adopted and microscopic examination is used to study surface of the sample.

The samples are immersed in solution for different times, these times are (0.5-1-1.5-2 hours).

The results have shown a continuous increase in corrosion rate with increase the temperature of used solution from 300C to 800C and this increase is almost linear.

It is also concluded that the corrosion rates of used alloy increase when the immersion time increase from 0.5 to 2 hours.

In addition, the rates of corrosion raise when the (HCl) acidic solution concentration increase.
