| 英文摘要 | The formation of ternary composite oxides in a high-temperature environment has laid the foundation for the design of high-temperature wear-resistant self-lubricating film. A series of Pb-Cr-O films with different Cr contents were prepared by incorporating different ratios of Pb-Cr into a target in the reactive magnetron sputtering system. The results showed that the hardness of the Pb-Cr-O films is greatly improved compared to the pure Pb-O film. In addition, the Pb29Cr4O67 film with the highest Cr content forms an amorphous structure due to the accumulation of Cr6+ at the grain boundary, which improves the H/E and H-3/E-2 of the film. At 600 degrees C, in contrast with the single PbO lubricating phase formed by pure Pb33O67 film, the Pb29Cr4O67 film forms a composite lubricating phase of Pb5CrO8 and PbO. This leads to a decreased wear rate as low as 7.2 x 10(-6) mm(3)N(-1)m(-1) while maintaining low coefficient of friction comparable to pure Pb33O67 film. At higher temperature of 700 degrees C, Cr element in Inconel 718 matrix diffuses into the Pb-based oxide film and forms Pb5CrO8 phase similar to Pb29Cr4O67 film, which improves the wear resistance of the Pb33O67 film while maintaining low friction coefficient of 0.15. |
