An aluminum-alloy matrix reinforced with coated B4C particles was used for the present study. The cohesion of the reinforcing ceramic particles represents a very important factor, which is mostly poor at temperatures near the melting point of aluminum and leads to the inferior mechanical and tribological properties of the developed aluminum matrix composites with a non -uniform distribution of the reinforcement. The main reason for coating the particles is to improve the bonding between the reinforcement and the molten alloy and thus to eliminate any interfacial reactions. The great enhancement in the strength values of the composites in this study can be ascribed to the effective load-bearing capacity of the disintegrated B4C particles, which are adherently bonded to the matrix alloy. Homogeneity and a reduction in the particle size of the B4C during the extrusion process is evidenced in the microstructural studies"},{"@xml:lang":"sl","#text":"Članek je osredinjen na razvoj celovite metode za optimizacijo mehanskih in triboloških lastnosti kompozitov s kovinsko osnovo z uporabo optimizacije več strategij združevanja gruč delcev. Za študij je bila uporabljena Al-zlitina, ojačana z obloženimi delci B4C. Kohezija oplaščenih keramičnih delcev za utrjevanje je pomembna: navadno je slaba pri temperaturah blizu tališča aluminija in povzroča slabše mehanske in tribološke lastnosti razvitega kompozita na osnovi Al z neenakomerno razporeditvijo delcev za ojačanje. Glavni namen oplaščenja delcev je izboljšanje povezave med delcem za ojačanje in staljeno zlitino ter odprava reakcij na površini stika. Veliko povečanje trdnosti kompozita v tej študiji se lahko pripiše učinkoviti nosilnosti razpadlih delcev B4C, ki so adherentno vezani na osnovno zlitino. Študije mikrostrukture so pokazale homogenost in zmanjšanje delcev B4C med iztiskovanjem"}],"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-ELGJXR6I","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-ELGJXR6I"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-ELGJXR6I/490c94ee-bb1f-46b7-8811-99818af2cfb8/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-ELGJXR6I/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-ELGJXR6I"}}}}
