摘要
采用粉末冶金法制备Fe-5(Cu-10Sn)-石墨-P-MoS2含油材料,研究石墨、P与MoS2的添加量对材料摩擦性能的影响。摩擦实验在150℃(±10℃)条件下进行,线速度分别为0.25,0.50和0.75m/s,逐级加载,每间隔10min增加10MPa,从10MPa加载至50MPa。结果表明:材料的摩擦因数随石墨添加量增加而减小,当石墨添加量达到1.5%后,摩擦因数基本稳定在一个较低值上;P添加量以0.3%为宜,较低和较高均导致摩擦因数不稳定;摩擦因数随MoS2添加量增加而减小,当MoS2添加量为1.5%时,材料具有稳定且较小的摩擦因数,随载荷和线速度增加,摩擦因数持续减小。
Fe-5(Cu-10Sn)-graphite-P-MoS2 oil-containing materials were prepared by powder metallurgy. The effects of graphite, P and MoS2 contents on the tribological properties of the material were studied. The friction tests were carried out at 150 ℃(±10 ℃) with linear velocity of 0.25, 0.50 and 0.75 m/s. The loading ranges from 10 MPa to 50 MPa, which increasing by 10 MPa every 10 minutes. The results show that the friction coefficient of the material decreases with the increase of C content. When the C content reaches 1.5%, the friction coefficient is basically stable at a lower value. The addition amount of P is preferably 0.3%, and both lower and higher results in unstable friction coefficient of the material. The friction coefficient of the material decreases with the increase of MoS2 content. When the MoS2 content is 1.5%, the material has a stable friction coefficient, and the friction coefficient shows a steady decrease with the increase of load and linear velocity.
