耐磨性是材料重要的机械性能之一 .文中采用国产MM_2 0 0型摩擦磨损试验机对新型Grp·Al2 O3_SiO2 (sf) /ZL10 9复合材料进行了干滑动摩擦磨损试验 ,并探讨了石墨在其中的作用 .同时采用HB_30 0 0型布氏硬度计测定了与摩擦磨损性能相关的硬度指标 .
Abrasion resistance is one of the important mechanical properties of the material.The dry sliding friction and wear tests of the new Grp · Al 2 O 3 -SiO 2 (sf) / ZL 10 9 composites were carried out with a domestic MM 2 0 0 friction and wear tester, Which the role of the same time using HB_30 0 0 Brinell hardness measured with the friction and wear properties of the hardness index.
