使用Ni基（Ni53Nb20Ti10Zr8Co6Cu3，数字以.%表示）金属玻璃（MG）。由于MG的上级耐磨性，齿轮电机的耐久性得到改善。为了阐明镍基MG的上级耐磨性，进行了简化的滑动磨损和滚动磨损试验。在滑动磨损条件下，镍基MG的磨损量大于SK钢，而在滚动磨损条件下，镍基MG具有上级耐磨性。因此，在连续改变接触面的滚动条件下，可以获得较好的耐磨性。对镁合金和钢的磨损机理进行了比较和讨论。(c)2006年由Elsevier B.V.出版
A microgeared motor with a diameter of 2.4 mm was constructed using a Ni-based (Ni53Nb20Ti10Zr8Co6Cu3, numbers indicate at.%) metallic glass (MG). The durability of the geared motor was improved due to superior wear resistivity of the MG. In order to clarify the superior wear resistivity of the Ni-based MG, simplified sliding-wear and rolling-wear tests were performed. The wear loss of the Ni-based MG under sliding-wear condition was larger than that of SK-steel, while the Ni-based MG exhibits superior wear resistance under rolling-wear condition. It is therefore concluded that better wear resistivity can be obtained under rolling condition which changes contact surface continuously. Wear mechanisms of MG and steel are compared and discussed.
