"The abrasive wear resistance of the Fe64Co30Si3B3, Co86.5Cr4Si7B2.5, Fe73.5Nb3Cu1Si13.5B9, and Fe82.6Nb5Cu3Si8B1.4 commercial amorphous alloys (ribbon 0.03 mm thick and 12 mm wide) has been investigated under the conditions of abrasive and adhesive wear upon sliding friction. The character of fracture of the surface and structural transformations that occur in these materials upon wear have been studied by the metallographic and electron-microscopic methods," scientists in Russia report.
"It has been shown that at room and cryogenic (-196A degrees C) temperatures of tests the abrasive wear resistance of the amorphous alloys is two-three times lower than that of ...
