vizuelno, na dnevnoj svetlosti, pod uglom od45º. Površina prevlake kod svih uzoraka je sjajna iglatka. Nema dendrita, pregorelih i nepokrivenihmesta.Debljina prevlake cinka je merena na 15 mestaprema datom planu na slici 1. Na graficima, naslici 4, na osnovu rezultata merenja, prikazana jeraspodela debljine prevlake po površini uzorka.Na osnovu ovih grafika se može zaključiti dadebljina po širini i dužini uzorka odstupa ineravnomerna je. Najveće vrednosti za debljinuprevlake su izmerene na središnjem delu uzorka nadužini 13,5 mm od početka. Početak uzorka jeoznačen tačkom "A". To je tačka koja označavagornju stranu uzorka pri nanošenju cinka.Debljina prevlake, µm30252015105Širinauzorka,mm1.558.5Ispitivani uzorci su zadovoljili zahteve standarda.Prianjanje nanetih prevlaka cinka je dobro, nisuuočene promene na prevlaci cinka koje bi ukazalena odvajanje prevlake od osnovnog materijala,podloge.Koroziona stabilnost prevlaka cinka određivanaje praćenjem uzoraka tokom dužeg vremenaizlaganja dejstvu rastvora 3% Na Cl, u skladu saASTM B117-64 metodom. Ispitivani su uzorcirazličitih karakteristika (hrapavost i tvrdoćapodloge, debljina prevlake), tabela 2. Rezultatipraćenja korozione stabilnosti prevlaka cinka supokazali da nije došlo do pojave korozije, tako dase ne može uspostaviti veza između parametaraprethodne obrade i korozione otpornosti.Tribološkim ispitivanjima na tribometru blokon-diskmerena širina traga habanja na bloku i nataj način određivana otpornost na habanje kaoparametar habanja površini sa prevlakom cinka naispitivanim blokovima (slika 5).01.5 4.5 7.5 10.5 13.5Dužina uzorka, mma) uzorak 45Debljina prevlake, µm252015105Širinauzorka,mm1.558.501.5 4.5 7.5 10.5 13.5Dužina uzorka, mmb) uzorak 118Slika 4.
