Wear Properties of Sc-Bearing Zr-Based Composite BMG with Nano-CuZr<sub>2</sub> under Lubrication
Abstrak
Lubricated sliding wear of amorphous (Zr<sub>55</sub>Cu<sub>30</sub>Ni<sub>10</sub>Al<sub>5</sub>)<sub>99.98</sub>Sc<sub>0.02</sub>/CuZr<sub>2</sub> nanocrystal composite bulk metallic glasses (BMG) under various sliding velocities with a load of 20 N was investigated using the pin-on-disk test. After the wear test involving oil lubrication was performed, there was no wear induced new-phase transformation in the sample surface. Friction coefficients were within the range from 0.22 to approximately 0.29 under a 20-N load at different sliding velocities. Therefore, the calculated friction coefficients clearly indicated that the adhesion wear dominated from the experimental results. This deformation behavior resulted in a higher wear rate and wear coefficient. In addition, worn surfaces were characterized and examined under a scanning electron microscope (SEM) and optical microscope. The mechanism of high wear rate was clarified.
