<p>The friction maps and wear maps of Zr_62.5Fe₅Al₁₀Cu_{22.5−<i>x</i>}Nb_<i>x</i> (<i>x</i> = 0, 1.5, 2.5) bulk metallic glasses with different Nb contents and normal loads were constructed using the response surface classification study method. The results indicated that the wear mechanism transited from delamination wear to abrasive wear, with the increase in the Nb content and normal load. The addition of Nb improved the stability of friction coefficient curves and altered the wear rate-changing trend from increasing to decreasing with the increase in normal loads. Besides, the changing trend of wear rates with the increase in the Nb content was also altered at the same normal loads. 3D wear map extended upward at lower normal loads (3, 5 N), but it extended downward first and then slightly upward at higher normal load (7 N). The wear mechanism, friction coefficient and wear rate of Zr_62.5Fe₅Al₁₀Cu_{22.5−<i>x</i>}Nb_<i>x</i> bulk metallic glasses were predicted by the wear maps with different Nb contents and normal loads.</p>
