The fluidity of molten metal is very important in producing sound castings, particularly thin-wall castings. In the gravity casting of thin-wall castings of the Al4-1 alloy, the melt that fills the mold with the effect of self-weight, does not have sufficient fluidity, so causing defects such as cold shut, misrun and shrinkage defects during the solidification. These defects reduce the quality and mechanical properties of the cast parts. The casting fluidity depends on many factors, such as temperature, melt composition, casting part shape and mold coating. This study reports the influence of a nano-ceramics mold coating, a micro-ceramic mold coating, a graphite mold coating and the section thickness of the part on the fluidity length of Al4-1 alloy castings. The results showed that by applying nano-ceramic mold coatings on the surface of a sand mold, the fluidity length and the surface quality of the castings can be improved"},{"@xml:lang":"sl","#text":"Tankostenski ulitki iz aluminijevih zlitin so nova priložnost za letalsko industrijo pri proizvodnji lahkih ulitkov z dobrimi mehanskimi lastnostmi. Tekočnost staljene kovine je pomembna pri proizvodnji ulitkov brez napak, posebno še tankostenskih. Pri gravitacijskem ulivanju tankostenskih ulitkov iz zlitine Al4-1 talina zapolni formo zaradi lastne teže, če pa nima dovolj tekočnosti, to povzroči nastanek napak, kot so hladni zvari, slabo tečenje, napake zaradi krčenja pri strjevanju. Omenjene napake zmanjšujejo kvaliteto in mehanske lastnosti ulitkov. Livnost zlitine je odvisna od mnogih dejavnikov, kot so temperatura, sestava taline, oblika ulitka in prevleka forme. Predstavljen je vpliv nanokeramičnega premaza, mikrokeramičnega premaza, grafitnega keramičnega premaza in lokalne debeline na tekočnost v ulitkih iz zlitine Al4-1. Rezultati so pokazali, da je mogoče z uporabo nanokeramičnega premaza na peščeni formi izboljšati tekočnost in kvaliteto površine ulitka"}],"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-PZS5UIJ6","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-PZS5UIJ6"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-PZS5UIJ6/8d8c759b-aabc-457e-baf4-d4ddd20af981/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":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-PZS5UIJ6/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-PZS5UIJ6"}}}}
