Effects of environment on the sliding tribological behaviors of Zr-based bulk metallic glass

Tribological behavior of Zr-based bulk metallic glass sliding against polymer, ceramic, and metal materials

“…4 (d) illustrated the oxidation of wear debris during the friction process. The oxidation of the worn BMG surfaces had also been reported by many other works [24,32,33]. The wear rate of the BMG specimens significantly increased with increased oxygen content in the testing environment [32,33].…”

“…The oxidation of the worn BMG surfaces had also been reported by many other works [24,32,33]. The wear rate of the BMG specimens significantly increased with increased oxygen content in the testing environment [32,33]. According to wear debris analysis results, Fu [24] indicated that a thin layer of oxide was broken and mixed with unoxidized BMG during continued plastic deformation.…”

Tribological behaviors of Zr-based bulk metallic glass versus Zr-based bulk metallic glass under relative heavy loads

“…The sliding distance, however, was found to have a much lower effect on the tribological behaviors [30]. Wu et al [32] conducted a series of experiments under different atmosphere conditions and reported that the wear rate increased with the oxygen concentrations. Duan et al [33,34] studied the tribological properties of Ti-and Zr-based BMGs in dry condition and different solutions (deionized water and hydrogen peroxide with different concentrations).…”

Enhanced Wear Resistance of Zr-Based Bulk Metallic Glass by Thermal Oxidation Treatment

“…This result indicate that surface oxidation happened during the sliding, however, the oxidized scale formed during the sliding process is inhomogeneous. Surface oxidation also took place in some other studies for Zr-based BMGs under dry-sliding tests 4,8,14) , which may be caused by the high ash temperature generated on the friction surface 11,14) . In Fig.…”

“…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) .…”
