【Abstract】 In this paper, the effects of graphite particle size on the friction and wear properties of Cu-Fe matrix friction materials are investigated. The results show that, with decreasing graphite particle size, the hardness of the material increases and the strength decreases, but the wear rate of the material and frictional pair increases, it has also been found that the coefficients of friction (μ) changes slightly with decreasing graphite particle size.更多还原
