performed in each environment. The phases of the specimens both before and after wear testing were analyzed on a Rigaku D/Max 2000 X-ray diffractometer (XRD) with Cu Kα radiation operated at 40 kV and 300 mA...-stabilized zirconia counterface. It was found that the wear of the Zr-based BMG was reduced by more than 45% due to the removal of oxygen from the test environment at two different loads, i.e., 16 N......

running. The tests were carried out for 3 h; then the specimens were removed from the wear testing machine and cleaned with alcohol, in order to remove all the attached worn particles, and then the mass... of 1000 r/min using a pin-on-disk wear testing apparatus. The focus was on the influences of the FSW processing parameters (tool geometry, rotational speed, and welding speed) on the wear......
