Abstract

Oil lubricated sliding wear of a (Cu₅₅Zr₄₀Al ₅)₉₈Er₂ amorphous/(Zr₂Cu, AlCu) crystal bulk metallic glass (BMG) composite under different loads and velocities was studied with the pin-on-disk tests. The results demonstrated that load and sliding velocity significantly affected the wear characteristics of the BMG composite. The coefficient of friction ranged from 0.15 to 0.23 under loads of 10 N-30 N with different sliding velocities. Above a load of 30 N, all the coefficients of friction increase rapidly to higher values for various sliding velocities. It is found that the influence of load is greater than that of sliding velocity, and the dominant wear mechanism of this material is adhesive wear.
