| 中文摘要: |
| 金属-陶瓷复合镀层可以显著改善的硬度、致密性、耐蚀性、耐磨性以及抗高温氧化性能等可显著得到改善，应用范围广泛。综述了影响复合镀层性能的几大因素，重点介绍了增强相粒子粒径、表面活性剂类型、制备镀层的沉积方式以及第二相颗粒种类对电沉积复合镀层性能的影响。陶瓷颗粒尺寸影响复合镀层的性能，细小颗粒对镍基复合镀层具有细晶强化作用，微米级陶瓷颗粒能够大大改善Ni基复合镀层的力学性能。超细纳米陶瓷颗粒作为增强相，可以显著提高复合镀层的耐蚀性，添加纳米颗粒的复合镀层的显微硬度优于添加微米颗粒复合镀层。非离子表面活性剂能提高第二相颗粒在镀层中的复合量及在镀液中的分散性，有利于获得高硬度的复合镀层，进而提高整个镀层的耐磨性和耐蚀性。超声波-脉冲电沉积法得到的复合镀层形貌更平整，晶粒更细小，结构更致密，且得到的复合镀层硬度更高，耐磨性、耐蚀性更好。与SiC复合镀层相比，SiO2复合镀层具有更好的耐蚀性和抗氧化性。最后，分析展望了颗粒增强镍基复合材料的应用前景及未来研究的重点。 |

| Metal ceramic composite coating can significantly improve hardness, density, corrosion resistance, wear resistance and high temperature oxidation resistance of the coating, and has a wide range of application. Some factors affecting properties of composite coatings were reviewed, effects of reinforced-phase particle size, type of surfactant, deposition mode and type of second-phase particles on properties of electrodeposited composite coating were emphatically introduced. The ceramic particle size affected properties of the composite coating, fine grains had effect of refined crystalline strengthening on Ni-based composite coating. Micron-grade ceramic particles could greatly improve mechanical properties of the Ni-based composite coating; corrosion resistance of the composite coating could be significantly improved using ultrafine ceramic particles in reinforced phase. Microhardness of the composite coating with nano particles was superior to that of composite coating with microparticles. Nonionic surfactant could improve compound quantity of the second-phase particles in the coating and dispersibility in plating solution, which contributed to high-hardness composite coating, thus improving wear resistance and corrosion resistance of the whole coating. Morphology of the composite coating prepared in ultrasonic-pulse electrodeposition method was more smooth, the grain was finer, the structure was more compact, and the composite coating was harder, and wear resistance and corrosion resistance were better. Compared with SiC composite coating, SiO2 composite coating exhibits better corrosion resistance and oxidation resistance. Finally, application prospect and future research focus of particle-reinforced nickel-based composite materials were analyzed. |
