Abstract :
Bearing rollers, 7.5 mm in diameter and 7.5 mm in length, were prepared from Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass (BMG). The working life of the bearing rollers was evaluated through a real rotation test with a large-load and at a high-speed, and compared with that of commercial GCr15 steel rollers. The results show that the bearing rollers of Zr-based bulk metallic glass have a better wear resistance than the commercial GCr15 ones. And the wear behaviors are different for these two kinds of bearing rollers.
