Abstract
Diplomski rad sastoji se od teorijskog i eksperimentalnog dijela. U teorijskom dijelu je definiran pojam korozije, opisani pojavni oblici korozije, te metode zaštite od korozije. Detaljno su opisani zaštitni organski premazi i njihove komponente, kao i vodorazrjedivi premazi. Na kraju teorijskog dijela spomenuta je upotreba kitozana kao aktivne komponente u premazima. U eksperimentalnom dijelu provedena su ispitivanja korozijskog ponašanja na brušenim i poliranim uzorcima čelika Č.4230 u 5% otopini solne kiseline. Ispitivanja na koroziju su izvršena s četiri vrste premaza: otopinom kitozana, otopinom kitozana s eukaliptolom kao inhibitorom korozije, otopinom kitozana uz dodatak 5% praha TiO2, te otopinom kitozana uz dodatak 5% TiO2 i 100 μL eukaliptola na 100 mL pripremljene otopine. Premazi na bazi kitozana uz dodatak eukaliptola pokazali su zaštitno djelovanje, no njihovo zaštitno djelovanje zapravo kratkotrajno, pa bi se ovaj način zaštite mogao primjeniti samo kao privremena zaštita čelika.
Abstract (english)
Thesis consists of a theoretical and an experimental part. The theoretical part defines the concept of corrosion, describes the manifestations of corrosion, and methods of corrosion protection. Protective organic coatings and their components, as well as water-soluble coatings, are described in detail. At the end of the theoretical part, the use of chitosan as an active component in coatings is mentioned. In the experimental part, corrosion behavior tests were performed on ground and polished samples of Č.4230 steel in 5% hydrochloric acid solution. Corrosion tests were performed with four types of coatings: chitosan solution, chitosan solution with eucalyptol as a corrosion inhibitor, chitosan solution with 5% TiO2powder, and chitosan solution with 5% TiO2 and 100 μL eucalyptol per 100 mL of prepared solution. Chitosan-based coatings with the addition of eucalyptol have shown a protective effect, but their protective effect is actually short-lived, so this method of protection could only be applied as a temporary protection of steel.
