Abstract

Tema ovog rada je ispitivanje utjecaja aditivne proizvodnje električnim lukom i žicom (WAAM) na korozijsku otpornost niklove legure Inconel 625.
U prvom dijelu rada obrađene su niklove legure i njihova mehanička i kemijska svojstva. Poseban naglasak stavljen je na leguru Inconel 625 te je navedena najčešća primjena istih.
Opisana je aditivna proizvodnja sa naglaskom na postupke zavarivanja (navarivanja) električnim lukom i žicom (WAAM) . Također opisani su osnovni postupci ispitivanja korozijske postojanosti materijala.
U eksperimentalnom dijelu rada ispitan je kemijski sastav i korozijska postojanost jednog uzorka u izvornom stanju, i dva uzorka izrađena aditivnom proizvodnjom električnim lukom i žicom (WAAM) iz legure Inconel 625.

Abstract (english)

The topic of this thesis is testing the influence of additive production with arc and wire (WAAM) on the corrosion resistance of Inconel 625.
The first part of the thesis includes an overview of nickel alloys and their mechanical and chemical characteristics. Particular emphasis was placed on nickel alloy Inconel 625, and it is described the most common application. Furthermore, it is made an overview of additive manufacture with an emphasis on arc welding (WAAM) and basic procedures of testing the corrosion resistance of materials.
The experimental part of the thesis is testing chemical composition and corrosion resistance of one sample in its origin state, as well as two samples made with additive production with electric arc and wire (WAAM).
