The mechanisms of structure formation in Al-Si alloys during laser cladding were studied. Particle size distribution, surface morphology and microstructure of the initial powders were investigated. The influence of the chemical composition of the powder material on the structure and the microhardness of the coating has been shown, as well as the influence of processing parameters on the microstructure and the geometry of the resulting tracks. Conclusions about the technological possibility of manufacturing single tracks with widths of &lt; 500 um based on an Al metallic matrix bearing a Si content ranging from 30 to 60 wt.% Si have been made</dc:description><dc:description xml:lang="sl">Avtorji v članku preučujejo možnosti enoslednega laserskega mikronavarjanja kompozitov s kovinskim matriksom na osnovi aluminijevih zlitin. Lasersko navarjanje zlitin Al-Si je v zadnjih desetletjih pritegnilo veliko pozornosti, saj s hitrim strjevanjem zagotavlja fino strukturo zlitin Al-Si in posledično boljšo protiobrabno obstojnost. Pri vseh dosedanjih eksperimentih je bila uporabljena širina sledi približno 3 do 5 mm, medtem ko lahko sodobni laserji fokusirajo laserski žarek v točki premera 50 um in z njimi je torej mogoče ustvarjati tudi objekte na mikrometrski skali. Brizganje prašnatih delcev je sicer težko nadzorovati, zlasti pri materialih z manjšo gostoto, prav tako pa ni objav o uspešnih izkušnjah z mikronavarjanjem lahkih materialov. Preučiti je treba tudi absorpcijo laserskega žarka in oblikovanje sledi med mikronavarjanjem</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-II58MFZF"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-II58MFZF" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-II58MFZF/2d66d288-e4af-4dd9-93e4-bd0c32d5f0b0/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-II58MFZF/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-II58MFZF" /></ore:Aggregation></rdf:RDF>
