The friction stir-welding (FSW) process and tool parameters play a key role in determining the joint's characteristics. In this paper, the corrosion resistance of a friction stir-welded alloy was studied via polarization and electrochemical impedance spectroscopy in 3.5% NaCl. The microstructure of different positions along the thickness of the aluminium alloy plate has been investigated with regard to varying parameters, including rotary speed and transverse speed. The heat-affected zones of the weld exhibited the highest susceptibility to inter-granular corrosion. The results also show that sound joints in AA7075 can be achieved using friction stirwelding. Corrosion resistance decreases with the increase of traverse speed from 0.37 to 0.76 mm/s at a rotary speed of 800 rpm. Corrosion resistance at a rotary speed of 1000 rpm is lower than that at 1200 rpm; an increase in the corrosion resistance may also be reached via the breaking down and dissolution of the inter-metallic particles"},{"@xml:lang":"sl","#text":"Prispevek pri tem raziskovalnem delu je bila preučitev vpliva procesnih parametrov na korozijsko obstojnost aluminijeve zlitine AA7075, varjene z gnetenjem. Varjenje z gnetenjem (FSW) je v primerjavi z navadnim laserskim varjenjem, ki spada med talilne postopke, okolju prijaznejša in energijsko varčnejša tehnologija. Varjenje z gnetenjem je bilo uporabljeno tudi v eksperimentih in analizah izboljševanja korozijske obstojnosti. Aluminijeva zlitina AA7075 (Al-Zn-Mg-Cu) je ena od najmočnejših aluminijevih zlitin, ki se danes uporablja v industriji. Zaradi dobrega razmerja med trdnostjo in težo ter njenih značilnosti naravnega staranja je lahko primerna za številne dele letalskih konstrukcij. Pri postopku varjenja z gnetenjem se plastično stanje kovine doseže s posebej zasnovanim valjastim orodjem z ramenskim delom in varilnim čepom malega premera, ki se vrti med dvema sočelno staknjenima površinama in tako ustvari močan zvarni spoj"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-999O6NEI","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-999O6NEI"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-999O6NEI/0cd29a60-cacf-41e1-bd6e-fc4886d0f69c/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-999O6NEI/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-999O6NEI"}}}}
