Abstract

Diplomski rad sastoji se od teorijskog i eksperimentalnog dijela.

U teorijskom dijelu rada obrađeni su mehanizmi mehaničkog oštećivanja, zaštita čeličnih konstrukcija premazima te najčešće korištena veziva za organske premaze, s naglaskom na epoksidne premaze. Navedena su njihova najvažnija svojstva te područja primjene.

U eksperimentalnom dijelu rada provedena su laboratorijska ispitivanja na uzorcima od niskougljičnog čelika. Ispitana su fizikalna svojstva i svojstava korozijske otpornosti tri vrste dvokomponentnih epoksidnih premaza nanijetih na ispitne uzorke. Ispitivanje fizikalnih svojstava temeljilo se na abrazijskoj i erozijskoj otpornosti na trošenje, otpornosti na udar, tvrdoću te prionjivost premaza, dok je ispitivanje svojstava korozijske otpornosti premaza provedeno u vlažnoj komori.

Abstract (english)

Thesis consists of theoretical and an experimental part.

The theoretical part of the paper deals with the mechanisms of mechanical damage, protection of steel structures with coatings and the most commonly used binders for organic coatings, with emphasis on epoxy coatings. Their most important properties and areas of application are listed.

In the experimental part of the paper, laboratory tests were performed on low-carbon steel samples. The physical properties and corrosion resistance properties of three types of two - component epoxy coatings applied to the test specimens were investigated. Testing of physical properties was based on abrasion and erosion resistance to wear, impact resistance, hardness and adhesion of the coating, while testing of corrosion resistance of the coating was performed in a humidity chamber.
