采用粉末冶金方法制备铜基摩擦材料,研究钛的添加量对材料的摩擦磨损性能的影响。结果表明:随着钛质量分数由3%增加到12%,铜基摩擦材料的相对密度提高,硬度增加。钛的添加导致晶格畸变,材料硬度提高。随着摩擦速度增加,材料的摩擦因数减小。钛添加到铜基摩擦材料中,降低了铜基摩擦材料的摩擦因数和磨损量,原因在于钛提高了材料的硬度,增加了表面微凸体强度,减少了犁削程度,从而降低了摩擦面的损伤程度,提高了材料的耐磨性。
The copper-based friction material was prepared by powder metallurgy method, and the effect of titanium addition on the friction and wear properties of the material was studied. The results show that as the mass fraction of titanium increases from 3% to 12%, the relative density of the copper-based friction material increases and the hardness increases. Titanium addition leads to lattice distortion, material hardness increases. As the friction speed increases, the friction coefficient of the material decreases. The addition of titanium to the copper-based friction material reduces the friction factor and wear of the copper-based friction material because titanium increases the hardness of the material, increases the asperity strength of the surface, reduces the extent of plowing, and reduces the friction surface The degree of damage, improve the wear resistance of the material.
