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 decomposed to Ag and MoO3 during sintering process. The tribological properties composites were evaluated, effects incorporation on friction wear characteristics analyzed. results deteriorated increasing temperature, decreased coefficient rate at medium high temperatures. containing 20 wt% lowered 0.33 1.51 × 10−5 mm3 N−1 m−1, respectively. mechanism characterized plastic deformation delamination. In addition, improvement temperatures is attributed syn...
