Abstract

Lead alloys including pure pb, pb – Sn, pb – Se and pb – Sn – Se
were prepared which confirmed by X – Ray. Corrosion potential and corrosion
current density and then the general kinetic behavior for corrosion were studied in
the temperature range 293 – 313 K in 5M sulfuric acid solution. The results
indicated that the rate of corrosion for all alloys increased with the rise of
temperature. The general kinetic behavior of the alloys followed the well known
Arrhenius equation. The values of log A and Ea effected by adding Tin and
Selenium, thus decreasing or increasing the rate of corrosion for alloys. A linear
relationship was found to exist between the values of Arrhenius equation log A and
Ea which is found to describe the corrosion activity of the alloys.
