Abstract
Delo obravnava problem vpliva protikorozijskih zaščit na visoko trdnostna jekla pri dinamičnem obremenjevanju. Opisani so tipi korozije in njihovi vplivi ter najpogostejše protikorozijske zaščite jekel v avtomobilski industriji. Cilj je bil ugotoviti ali protikorozijska zaščita z galvanskim cink-nikljanjem in barvanje s kataforezo vpliva na dobo trajanja zvarjencev. Z utrujanjem vzorcev smo ugotovili, da obstaja vpliv Zn-Ni zaščite, medtem ko je vpliv kataforeze zanemarljiv. Dobo trajanja jekel z različnimi protikorozijskimi zaščitami smo napovedovali tudi s programom FEMFAT.

Title:Estimating durability of dynamically loaded weld joints with anticorrosion protection
Abstract:
This master thesis discusses an impact of the anti-corrosive protection on dynamically loaded high-strength steel. The main types of corrosion, its effects, and most common anti-corrosive protection of steel in the automotive industry are described. The main objective was to see if the zinc-nickel electrodeposited coating and the cataphoresis coating affect the dynamically loaded welded specimens. The conclusion was that there is an effect of the zinc-nickel coating, however, the cataphoretic coating has no effect. The duration of the steel with various anti-corrosive protection has been predicted by the FEMFAT software.

Keywords:fatigue strength, high strength steels, Wöhler curve, zinc-nickel electrodeposition, electrophotetic painting
