السلوك الكهروكيميائي للفولاذ الأوستنيتي المقاوم للصدأ 316 في أنواع مختلفة من حمض الفوسفور

الملخص EN

The corrosion behavior of Austenitic Steel 316 was investigated in different kinds of phosphoric acid using electrochemical techniques like Tafel polarization.

The corrosion rate of this alloy was calculated in different concentrations of different kinds of phosphoric acid.

Measurements & tests have revealed that the effect of polluted phosphoric acid at this alloy is greater than the pure phosphoric acid.

Laboratory tests showed the change in both corrosion rate and corrosion current densities ( Icorr ) according to the change in phosphoric acid´s concentration.

This research showed the great importance for following studies of the effect of polluted phosphoric acid, produced in general fertilizer company, on the equipments and machines used for its production, because of its high corrosion rates that create many corrosion problems in these equipments and machines.
