ortodontske žice, SS 8/8, otpornost na koroziju, sok tablete Digene, veštačka pljuvačkaApstrakt
Stomatolozi koriste ortodontske žice kao što su SS 18/8, SS 316, Ni-Cr itd. za regulaciju rasta zuba U okružen u pljuvačke ove žice podležu koroziji Osim toga, podvrgava u se koroziji usled uzimanja hrane, sokova i tableta Otpornost na koroziju legure SS 8/8 u veštačko pljuvački (AS), u odsustvu i prisustvu soka Digene tablete, ispitana je tehnikama polarizacije i impedanse naizmenične struje Zaključuje se da se otpornost legure SS 8/8 na koroziju u veštačko pljuvački smanjuje u prisustvu Digene tablete Ovo je izloženo smanjenjem vrednosti otpora linearne polarizacije (LPR), vrednosti otpora prenošenja naboja (Rt), vrednosti impedanse i povećanjem korozione struje i vrednosti dvoslojne kapacitivnosti (Cdl). U prisustvu tablete Digene, vrednost LPR se smanjuje sa 3488228 na 1629535 Ohmcm2 . Vrednost struje korozije se povećava sa 1,447 k10-8 na 2,637k10-8 A/cm2 . Vrednost otpora prenosu naboja (Rt) opada sa 37796 na 10481 Ohmcm2 . Vrednost kapaciteta dvostrukog sloja povećava se sa 1.349k10-10 F/cm2 na 4.866k10-10F/cm2 . Vrednost impedanse se smanjuje sa 4,857 na 4,428. Stoga implicira da bi ljudi sa ortodontskom žicom od legure SS 18/8 trebali izbegavati oralno uzimanje soka Digene tablete.Reference
