摘要

1. Phosphorus additives studied had a generally good effect in reducing wear as measured by the Fretting Wear and SRV Wear test especially in the unadditized lithium complex core grease. 2. The high load and test temperature along with the low load of the HFRR Oscillating Wear test likely creates a more severe test regime in which the concentrations and types of chemistries are not as effective in preventing wear. 3. In general, the commercially balanced formulations had their performance lowered by the addition of competing surface active phosphorus additives. Only the Fretting Wear test gave a better performance with some of the phosphorus top treats in these greases. 4. There was no statistically significant correlation, in this study, between any of the performance tests investigated including penetration, 4 ball wear and friction along with the key fretting wear tests. A more detailed study needs to be undertaken to investigate the effect of test type and severity, additive chemistry and thickener interactions in order to better understand the mechanism by which additives can ameliorate the fretting wear of metal surfaces.

HFRR振荡磨损测试的高负载和测试温度以及低负载可能会创建更严格的测试方案，其中化学物质的浓度和类型不能有效地防止磨损。 3.通常，通过添加竞争性表面活性磷添加剂，商业平衡配方的性能会下降。在这些润滑脂中，只有一些微调的磷表面处理剂才能使微动磨损试验获得更好的性能。 4.在这项研究中，所研究的任何性能测试（包括击穿，4球磨损和摩擦以及关键的微动磨损测试）之间均无统计学意义的相关性。为了更好地了解添加剂可改善金属表面微动磨损的机理，需要进行更详细的研究以研究测试类型和强度，添加剂化学性质和增稠剂相互作用的影响。
