摘要/Abstract

摘要： 采用热压成型法制备有机制动摩擦材料,为了探究增摩填料ZrSiO₄、Al₂O₃在制动摩擦过程中的作用,用MM3000惯性台架摩擦磨损试验机测试所制备的摩擦材料的摩擦磨损性能,通过扫描电镜观测摩擦材料摩擦磨损后的表面形貌。结果表明:硬质填料具有良好的增摩作用;硬质颗粒在制动过程中有效的填充了摩擦材料表面的凹坑和空隙,在摩擦材料表面形成了稳定的表面膜,能够使受应力破裂的表面膜有规律的脱落,具有自洁净能力;摩擦过程伴随着热磨损、疲劳磨损和热磨损。

Abstract: The fiber reinforced organic friction materials are prepared by the way of thermoforming. In order to check the role of antifriction filler ZrSiO₄ and Al₂O₃ in organic friction material, friction and wear performance are tested using MM3000 inertial frame friction and wear tester. The surface morphology of the prepared friction materials was analyzed by scanning electron microscope (SEM). It turns out that antifriction fillers have the significant role in increasing friction coefficient; the hard particles could fill the pits and holes on the surface of the friction material, on which a stable surface film formed, they can also make the surface film fall off from the material surface regularly by stress rupture, which has self-cleaning capacity. The wear mechanism of friction material is abrasive wear and fatigue abrasion, accompanying with thermal abrasion.

Key words: reinforcing filler, friction and wear, friction stability, surface film
