| 英文摘要 | A high-temperature self-lubricating Ni-based composite was prepared with the addition of Ag2Mo2O7 by a powder metallurgy technique. X-ray diffraction (XRD) analysis showed that Ag2Mo2O7 decomposed to Ag and MoO3 during the sintering process. The tribological properties of Ni-based composites were evaluated, and the effects of Ag2Mo2O7 incorporation on the friction and wear characteristics of composites were analyzed. The results showed that the tribological properties of Ni-based composite deteriorated with increasing temperature, and the addition of Ag2Mo2O7 decreased the coefficient of friction and wear rate of Ni-based composite at medium and high temperatures. The coefficient of friction and wear rate of composite containing 20wt% Ag2Mo2O7 were lowered to 0.33 and 1.51 x 10-5 mm3 N-1 m-1, respectively. The wear mechanism was characterized by plastic deformation and delamination. In addition, the improvement of tribological properties of the Ni-based composite at high temperatures is attributed to synergistic lubricating effect of silver molybdate (reproduce in the rubbing process at high temperatures) and iron oxide (transfer from disk material to the pin). |
