“…Surface properties such as wear resistance should be taken into consideration in many engineering applications. The tribological behavior of Zr-based BMGs has been studied extensively [3][4][5][6][7][8][9][10][11][12][13][14] , however, the results in different works are controversial. In some cases, Zr-based BMGs show high wear resistance, better than their crystallized counterparts and some conventional engineering alloy such as GCr15 steel 5,7) , while in some other cases they exhibit no indication of superior tribological properties or even worse wear resistance than commonly used engineering materials like Al6061, 304 SS, 316 L SS and CoCrMo alloy 3,4,9,12) .…”
