Abstract (Croatian)

U radu je prikazana tehnologija zaštite od korozije zaštitnim premazima s visokim udjelom cinka koji zaštitu od korozije ostvaruju galvanskim učinkom. Detaljno su opisana svojstva zaštitnih premaza, naročito zaštitnih premaza s visokim udjelom cinka, usporedba cinkovih prevlaka, metode i zaštita na radu kod nanošenja premaza. U eksperimentalnom dijelu rada provedena su usporedna ispitivanja uzoraka četiri vrste epoksidnih premaza s visokim udjelom cinka različitih proizvođača. Cilj je bio odrediti koji će od tih uzoraka pokazati najbolja zaštitna svojstva i kako im se mijenjaju fizikalna svojstva nakon izlaganja u slanoj i vlažnoj komori. Sukladno dobivenim rezultatima nakon izlaganja u komorama dodijeljena im je ocjena učinkovitosti zaštite od korozije.

Abstract

This thesis presents corrosion protection technology with zinc rich protective coatings which provide corrosion protection via galvanic effect. Properties of protective coatings especially zinc rich protective coatings, comparison with metal zinc coatings, techiniques and safety measures during coatings application are described in detail. Four different samples of epoxy zinc rich protective coatings were simultaneously tested during the experimental part of the thesis. The aim of the testing was to determine which one of the samples will provide the best anticorrosion properties and how do their mechanical properties change after being exposed in a hostile environment. Each of them got an anticorrosion efficiency grade according to the obtained results after exposure in the salt spray and humidity test chamber.
