Comparative Study Of Wear Resistance Of The Composite With Microhybrid Structure And Nanocomposite
European Journal of Molecular & Clinical Medicine,
2018, Volume 5, Issue 1, Pages 538-546
To compare microhardness and wear resistance of ceramic-polymer composites with micro and nanohybrid structures. The investigations employed commercial composites with nano-sized (Filtek Ultimate) and micro-sized (Filtek Z250) filler particles. A ball-on-disc micro-tribometer was used for testing.Microhardness was measured using the Vickers technique and the Futertech FM 700 equipment. Filtek Ultimate has been almost doubling the wear resistance of Filtek Z250 composite. The inclusion of filler nanoparticles enhanced the material's wear resistance. Also, there is no association between material microhardness and wear resistance.
