Abstract 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.

Key words： tribology self-lubrication oil-containing graphite P MoS₂
