Abstract

Osnovni cilj ovog rada bila je karakterizacija intermetalnih spojeva u zavarenom spoju čelika prevučenog niklom (Hilumin) i aluminijske legure 1050. U teorijskom dijelu rada opisano lasersko zavarivanje raznorodnih materijala i utjecajni faktori pri zavarivanju. Detaljno su opisani intermetalni spojevi koji se mogu formirati prilikom zavarivanja aluminija i čelika.
U eksperimentalnom dijelu rada provedena je analiza makrostrukture i mikrostrukture te mjerenje mikrotvrdoće HV0,01 i HV0,025 zavarenih spojeva na disk laseru. Mikrostruktura je analizirana na svjetlosnom i pretražnom elektronskom mikroskopu. Također je provedena energetski disperzivna spektrometrija kako bi se odredili udjeli kemijskih elemenata u intermetalnim spojevima formiranim u metalu zavara. Utvrđeno je da se navedenim postupcima mogu pouzdano identificirati različiti intermetalni spojevi u metalu zavara.

Abstract (english)

The main objective of this thesis was the characterization of intermetallic compounds in the welded joint of nickel-plated steel (Hilumin) and aluminium alloy 1050. The theoretical part of the thesis describes laser welding of dissimilar materials and influential factors in dissimilar materials welding. Intermetallic compounds that can be formed during welding of aluminium and steel are described in detail.
In the experimental part of the thesis, macrostructure and microstructure analysis, as well as microhardness measurements HV0.01 and HV0.025 of disk laser welded joints, were performed. The microstructure was analysed using a light and scanning electron microscope. Energy dispersive spectrometry was also performed to determine the compositions of chemical elements in intermetallic compounds formed in the weld metal. It has been determined that the above methods can reliably identify various intermetallic compounds in the weld metal.
