상세내용 Abstract
Effects of Mo (1~7%) or Cr (2.3~8.3%) content on the friction and wear characteristics of Fe-based
bulk metallic glasses (BMGs) were investigated using a pin-on-disc-type tribo-tester, micro-hardness tester,
optical microscope (OM) and scanning electron microscope (SEM) with energy dispersive spectroscopy
(EDS). Tribo-oxidational behavior of a worn surface was also analyzed by X-ray photoelectron spectroscopy
(XPS). The friction coefficient was found to be less than 0.4 for Cr-containing BMG, which is lower than that
of Mo-containing BMG. As Mo content increased, the mass loss of BMG decreased gradually. In the case of
Cr content, the friction coefficient showed minimal change up to 6.3% composition, but significant reduction
at 8.3%. EDS and XPS results indicate the formation of an oxide film on the worn surface. This film was
identified as various iron oxides in all compositions, but as molybdenum at high composition and chromium
oxides at 2.3% and 8.3% compositions.
