摘要
采用热压成型的方法制备钢渣粉改性的树脂基摩擦材料,研究不同含量的钢渣粉对树脂基摩擦材料密度、硬度、冲击强度和摩擦磨损性能的影响,并通过扫描电镜观察磨损表面的微观形貌,分析其磨损机制。研究表明:随着钢渣粉含量增加,密度、硬度、冲击强度均呈现逐渐增加的趋势;钢渣能有效地改善树脂基摩擦材料的摩擦磨损性能和提高抗热衰退性能,当钢渣粉质量分数为20%时,能够提高材料的摩擦因数,降低磨损率,且材料综合性能最好;随着钢渣粉质量分数的增加,树脂基摩擦材料的磨损形式以黏着磨损和热磨损为主转变为磨粒磨损和热磨损为主。
Resin-based friction materials containing steel slag powder were prepared by dry heat-pressing process.The density,hardness,impact strength,friction and wear properties of the friction materials with different steel slag powder content were studied.The morphologies of worn surface of different friction materials were observed by using scanning electron microscopy（SEM）,and the wear mechanism was analyzed.The results show that the density,hardness and impact strength of friction materials is increased gradually with the increasing of the steel slag powder content.When the content of steel slag powder is 20%（mass fraction）,the friction materials have high friction coefficient and low wear rate,which exhibit the best comprehensive properties.However,when the content of steel slag powder is more than 20%（mass fraction）,the heat fading resistance of samples is decreased,showing that heat wear and abrasive wear are the main wear forms.
