Abstract
Tema ovog diplomskog rada je korozijska postojanost aluminijske legure dobivene postupkom aditivne proizvodnje električnim lukom i žicom (WAAM). Rad je podijeljen u dva dijela, prvi teoretski i drugi eksperimentalni. U teorijskom dijelu opisan je postupak proizvodnje aluminijskih legura, njihova podjela prema različitim kriterijima, kao i mehanička svojstva, korozijska postojanost s posebnim naglaskom na seriju 5xxx koja je kasnije ispitivana u eksperimentalnom dijelu. Navedeni su i opisani najčešći postupci zavarivanja aluminija, njihove karakteristike, ograničenja te zavarljivost aluminija. Prikazane su značajke aditivne proizvodnje, njihove prednosti, razvoj te je detaljnije opisana WAAM tehnologija s aluminijskim legurama. Nadalje, opisana je zasebno korozijska postojanost zavarenih spojeva aluminijskih legura, s najčešćim pojavnim oblicima korozije. U eksperimentalnom dijelu, opisana je izrada uzoraka, njihova naknadna obrada, prikazani su parametri pri izradi i dodatni materijal. Izrađena su četiri uzorka, od dvije legure s pomoću dva postupka zavarivanja. Ispitan je kemijski sastav izrađenih uzoraka te provedena makro i mikro analiza površina. Provedena su elektrokemijska ispitivanja, ispitivanje korozijske postojanosti uzoraka u slanoj komori te su analizirani i uspoređeni rezultati.
Abstract (english)
The theme of this thesis is the corrosion resistance of aluminum alloy obtained by the process of wire and arc additive manufacturing (WAAM). This study is divided into two parts, the first is theoretical and the second is experimental. The theoretical part describes the process of making aluminum alloys, classification of alloys according to different criteria, their mechanical stability, corrosion resistance with special emphasis on the 5xxx series, which was later tested in the experimental part. The methods of aluminum welding, their characteristics, limitations and weldability are also described. The features of additive production, their advantages, the development, and described WAAM technology with aluminum alloys in details is presented. A corrosion resistance of aluminum alloys welded compounds and the most common forms of corrosion are described separately in addition. Experimental part is describing pattern making with their post-processing. The parameters of the fabrication and additional material as well are presented. Four samples were made of two alloys using two welding processes. The chemical composition of the fabricated samples was examined and macro and micro surface analyses was performed. Electrochemical corrosion tests and salt spray chamber test were carried out and the results were analysed and compared.
