Abstract
In order to achieve improved mechanical properties of dispersion strengthened nanocomposite, without influencing electrical and thermal conductivity it is necessary for dispersoide to be nano sized and uniformly distributed in base metal matrix. In this paper are presented the results concerning possibility of using UV spectrophotometry for determination of alumina particle size in Cu- AL2O3 system. Presented results show that this method is unefficient as method for determination of dispersoide particle size, due to the coalescence of particles false results are obtained, i.e. particle size significantly higher then one determined by image analysis.
Izvod U cilju postizanja poboljšanih mehaničkih osobina disperzno ojačanih nanokompozita, bez uticaja na električnu i termičku provodljivost neophodno je da je dispergovana faza nano veličine i ravnomerno raspoređena u osnovnom metalu. U radu su prikazani rezultati vezani za mogućnost određivanja veličina čestica glinice u nanokompozitnim materijalima iz sistema Cu- AL2O3 primenom UV spektrofotometrije. Dobijeni rezultati pokazuju da je ova metoda nedovoljno pouzdana kao adekvatna metoda za određivanje veličine čestice diperzne faze, jer usled koalescencije čestica dolazi do pojave lažnih rezultata, tj. određena veličina čestica je višestruko veća od veličine određene analizom slike.
