| 中文摘要: |
| 通过在磷化液中加入纳米Al2O3的方法，在碳钢表面形成具有较高硬度和耐磨性的纳米Al2O3复合磷化膜，为需要耐磨性较高的齿轮、活塞环、轴承套、压缩机等运动承载件磷化提供了新的方法。通过电子探针、SEM、显微硬度仪及UMT-2显微磨损实验机等检测仪器对磷化液中纳米Al2 03颗粒含量对复合磷化膜中纳米颗粒复合量、磷化膜表面形貌、膜的显微硬度以及摩擦学性能的影响进行了研究。结果表明：随着磷化液中纳米Al2 03颗粒含量的增加，复合量增加，表面光滑，显微硬度提高，摩擦因数减小，减摩性增强。当磷化液中Al2O3颗粒含量为lOg/L时，磷化膜具有最佳的耐磨减摩性，进一步提高磷化液中的纳米颗粒含量，磷化膜性能反而下降。 |
| 英文摘要: |
| Nanometer Al203 composite phosphate film was formed on the surface of mild steel by adding Al203 nano-particles into the phosphate solution, which increased the hardness and wear resistance, which is a new method for phosphating treatment of gears, piston rings, bearing holders, compressor and other movement bearing items which need stronger tribological function. The effects of nano-Al203 particle content in the phosphate solution on the nano-particle content, microstructure hardness and wear resistance of the composite coating were studied by electro probe, SEM, micro-rigidity apparatus and UMT-2 micro-wear test machine. The results show that the composite volume and hardness of the composite coating are improved with the increase of the nano-particles in the phosphate solution, surface lubricity and antifriction of composite coating are enhanced. The nano-composite coating has the best wear resistance and antifriction function when the nano-particle content in the solution is lOg/L, above which the wear resistance and antifriction function decreas |
