Nkọwa: Nke a bụ obere hydrogen sodium kpuchie electrode pụrụ iche maka ígwè alumini.Jiri DCEP (nke dị ugbu a electrode ziri ezi), na enwere ike ịgbanye ya n'ọnọdụ niile na arụ ọrụ arc dị mkpụmkpụ.Enwere ike ịgbado J557SLA ozugbo na-ewepụghị oyi akwa alumini n'elu oghere tupu ịgbado ọkụ.Mana J557SLB kwesịrị iwepụ oyi akwa alumini n'elu oghere tupu ịgbado ọkụ.
Ngwa: A na-eji ya maka ịgbado ihe owuwu nchara alumini n'okpuru usoro corrosion nke hydrogen sulfide, sọlfọ, amonia, ammonium bicarbonate na hydrogen nitrogen na okpomọkụ na-arụ ọrụ n'okpuru 540 ° C.Dị ka ọkpọkọ mmiri ọkụ, ngwa nnụcha mmanụ ala, akụrụngwa fatịlaịza na ọkpọkọ uzuoku, wdg.
