| 摘要 | Extensive research efforts have been devoted to develop a new substance which could achieve effective lubrication in a broad temperature range. Pb(ReO(4))(2), composed of the double oxides of PbO and Re(2)O(7), exists in low shear strength. The anti-friction behavior of Pb(ReO(4))(2) was tested by Universal Micro-Tribotester (UMT-2M) with ball (Si(3)N(4)) on disc (superalloy) at elevated and declined temperature in the range of 22 degrees C to 600 degrees C. Composition of debris and morphologies of worn tracks were determined by X-ray diffraction (XRD) and scanning electron microscope (SEM), and contact resistance between the worn surface and steel ball was measured by UMT. The results show that Pb(ReO(4))(2) is a superior lubricant at elevated and declined temperatures, and the friction coefficient is much lower than that without lubricant. The superior lubricating properties should be attributed to the formation of an anti-frictional surface film. And higher temperature could result in the formation of a more complete and durable film. For Pb(ReO(4))(2) melts at 566 degrees C, the fused product is much easier to flow and generate a film which could separate the tribo-pairs perfectly. Subsequently, the lowest friction coefficient is gained at 600 degrees C, and good lubrication can be maintained till to 22 degrees C. |
