| 目的 研究热喷涂和喷丸新型复合技术涂层的组织结构和摩擦学性能。 方法 在发动机主要摩擦副零件表面制备涂层,对其表面和横截面组织进行金相和 SEM 观察分析, 对处理前后零件进行尺寸、硬度、摩擦系数及发动机台架试验测试分析。 结果 零件表面形貌得到明显改善,但涂层膜状组织不明显,新技术对零件尺寸和硬度影响不大,涂层使零件表面动摩擦系数略有增加,由 0 . 142 增加至 0 . 152 ,但其波动性变小,沉积涂层导致发动机的动力性和经济性变差。 结论 通过对复合工艺参数的调整, 将制得兼具热喷涂与喷丸两种工艺优势的涂层, 则热喷涂新技术将不失为一种优良的表面处理工艺。 |

| Objective To study the structure and tribological behavior of the new coating which was a complex of thermal spraying and shot peening. Methods The new coating was prepared on the surface of friction pair. To observe the structure of surface and cross section, the metallographic analysis and SEM were conducted. A series of tests were carried out on the size, hardness, friction coefficient and engine bench for the original and new parts. Results The surface morphology was significantly improved, but as for the membrane microstructure, the improvement was not obvious. The results were as follows: the coating had weak effect on the size and hardness of the parts, the kinetic friction coefficient increased slightly from 0. 142 to 0. 152 and had better stability, the engine performance and fuel efficiency declined. Conclusion Combining the property of thermal spraying and shot peening, competitive coating could be obtained through parameter adjustments on the compound process and the new coating will be a promising technology for surface treatment. |
