“…Many achievements have been made in impregnating porous carbon/graphite with nonmetals (such as resin) or metals (such as aluminum, copper, Babbitt metal and antimony) effectively compacting pores, improving material performance parameters such as oxidation resistance, strength and hardness, and enhancing applications in extreme operating conditions including high temperatures, heavy loads and high abrasion environments [2][3][4][5][6][7][8][9][10]. As an impregnating material, antimony is superior to others, and has become a recent focus in the field of impregnated carbon/graphite materials [1,[12][13]. The operating temperature and strength of graphite/antimony are much higher than those of impregnated resin products.…”

“…Furthermore, antimony is more cost effective than silver, copper, and other metals of higher strength and abrasion resistance [1]. The graphite/antimony material is recently applied in mechanical field but few public research results in the academic field [12,13]. So there are many challenges that need to be solved, both in industrial applications and in academic research.…”

Coal tar pitch is used as the raw material to prepare graphite/antimony composites, of which the mechanical performance, microstructure, element composition and tribological performance are investigated. Results indicate that the composite density, shore hardness, flexural strength, compression strength and porosity are 2.38g/cm 3 ,103.10Hs,91.65MPa,290.5MPa, and 0.65% respectively, representing physical property improvement of 17.65%-28.75%. In addition to C, the major composite elements are Sb, Si, Al and S, with relative amounts of 87.8%, 4.5%, 3.1% and 2.4%, respectively. Under experimental conditions, the average value friction coefficient is 0.120-0.158. The friction coefficient ranges from 0.08 to 0.149, when the load is 10-48MPa.the friction coefficient decreases gradually as the load increases. The average friction coefficient is equal to 0.141 and 0.114 when the rotating speed is equal to 200r/min and 500r/min, respectively; the friction coefficients declines gradually as rotating speed increases.
