Sažetak

Koroziono ponašanje i termička stabilnost epoksidnih kataforetskih prevlaka na mekom čeliku i mekom čeliku sa elektrohemijski taloženim polianilinom (PANI) ispitivani su primenom metoda spektroskopije elektrohemijske impedancije i termogravimetrijske analize. PANI film na mekom čeliku je dobijen elektrohemijskim taloženjem iz vodenog rastvora 0,5 mol dm-3 Na-benzoata I 0,1 mol dm-3 anilina pod galvanostatskim uslovima, gustinom struje od j = 1,5 mA cm-2. Epoksidne prevlake na mekom čeliku I mekom čeliku sa PANI dobijene su elektroforetskim taloženjem u uslovima konstantnog napona uz mešanje. Pokazano je da dvoslojna PANI/epoksidna prevlaka na mekom čeliku ima značajno veću korozionu stabilnosti u 3% rastvoru NaCl u odnosu na epoksidnu prevlaku.
