Strong dependence of relative humidity on the tribological behavior of Cu-Zr based BMGs in ambient air

Résumé

Bulk Metallic Glasses (BMGs) are recent materials (1980s) of great interest for industrials thanks to their exceptional mechanical properties, including high elastic limit and fracture toughness. However, their tribological behavior is still highly debated and misunderstood, with erratic conclusions between studies. The present study aims at demonstrating the influence of the relative humidity of ambient air on the friction and wear of BMGs. Results confirm that an environment with high humidity causes a significant decrease of the coefficient of friction, thanks to the formation of a specific tribolayer at the interface.
