    摘要:

    采用干压擦筛造粒法制备了炭黑造粒颗粒,研究了炭黑造粒颗粒质量分数对Cu-Fe摩擦材料显微组织、力学性能、摩擦性能的影响。结果表明:炭黑造粒颗粒易被压制成条状形态,当炭黑造粒颗粒质量分数较低时,其与金属基体能形成完整的界面,而含量较高时界面易出现孔洞和裂纹;随着炭黑造粒颗粒质量分数的增加,摩擦材料的力学性能先增加后降低、摩擦系数和磨损量均先降低后增加。当炭黑造粒颗粒质量百分数为5%时,摩擦材料的力学性能最大,摩擦系数最低,磨损量最小,材料的综合性能最佳。

    Abstract:

    :The carbon black granulated granules were prepared by dry pressing and sieving granulation.The effects of the mass fraction of carbon black on the microstructure, mechanical properties and tribological properties of Cu-Fe friction materials were studied. The results show thatthe carbon black granulated granules were easy to be pressed into strip shape.When the mass fraction of granulated carbon black is low, it can form a complete interface with the metal matrix, and the interface was prone to form holes and cracks when the content is high.With the increase of the the mass fraction of granulated carbon black, the friction coefficient and the wear loss decline initially and then increases,while the bending strength and compressive strengthof the materials show the opposite trend.In particular,When the mass percentage of granulated carbon black is 5%, the friction material exhibits the highest mechanical properties, the lowest friction coefficient, the minimum wear loss and the best comprehensive performance.
