Abstract
Budući razvoj tvrdih metala teži ka sve većoj upotrebi nano čestičnih prahova. Primjenjujući sofisticirane postupke konsolidacije postižu se značajna poboljšanja triboloških, toplinskih i mehaničkih svojstava tvrdometalnih alata koja su u radu opisana. Veziva u nanostrukturiranim tvrdim metalima su nužna kako bi se stvorila tekuća faza tijekom procesa sinteriranja. Najčešće korišteni vezivni materijal je kobalt (Co) čije su prednosti i nedostaci navedeni kroz rad. Također, kroz rad je analiziran i utjecaj vezivnog materijala Co koji ostvaruje najbolja mehanička svojstva u nanostrukturiranim tvrdim metalima, no sve su češća istraživanja uporabe ostalih alternativnih veziva. Stoga, analizom dostupnih podataka navedeni su razlozi reduciranja udjela kobalta ili njegovog potpunog uklanjanja iz nanostrukturiranih tvrdih metala te različite vrste veziva i njihov utjecaj na tribološka, toplinska i mehanička svojstava tvrdometalnih alata.
Abstract (english)
The future development of hard metals tends towards the increasing use of nanoparticle powders. Applying sophisticated consolidation procedures, significant improvements are achieved in the tribological, thermal and mechanical properties of carbide tools which are described in this paper. Binders in nanostructured hard metals are necessary to create a liquid phase during the sintering process. The most used binder material is cobalt (Co) whose advantages and disadvantages are listed throughout the paper. Also, the paper analyzes the influence of the binder material Co, which achieves the best mechanical characteristics in nanostructured hard metals, but there are more and more research on the use of other alternative binders. Therefore, the analysis of available data states the reasons for reducing the proportion of cobalt or its complete removal from nanostructured hard metals and different types of binders and their impact on the tribological, thermal and mechanical properties of hard metal tools.
