Graphite Dispersoids Enhance the Tribology of a Non-Ferrous Bulk Metallic Glass

Article Preview

Abstract:

The tribological properties of a Zr-based bulk metallic glass were improved via dispersion of graphite particles into the alloy matrix. It was observed that both graphite and carbide particle dispersion led to a significant decrease of the coefficient of friction, at least two times lower compared to the original bulk metallic glass. The increased merit of such enhanced tribological properties lies in their combination with the particle-reinforced material high yield strength. We determined that graphite and, especially, carbide dispersion lead to a significant decrease of the material’s coefficient of friction (COF).
