| 目的 通过制备氧化锌-氧化石墨烯(ZnO-GO)杂化材料并植入陶瓷涂层中，提升氧化石墨烯与涂层界面的结合强度，从而提高涂层的显微硬度和耐磨性。方法 利用一种简单的水热法制备了ZnO-GO杂化物，并通过X射线衍射分析(XRD)、傅立叶变换红外光谱(FT-IR)、拉曼光谱和扫描电子显微镜(SEM)对纳米杂化材料进行表征。此外，使用溶胶凝胶法在不锈钢上制备添加不同含量ZnO-GO杂化材料的磷酸盐陶瓷涂层(CBPCs)。通过磨损试验研究陶瓷涂层的磨损行为，并观察涂层的磨损形貌，探讨ZnO-GO涂层的磨损机理。结果 X射线衍射(XRD)、傅里叶红外光谱(FTIR)、拉曼光谱(Raman)和扫描电子显微镜(SEM)的分析结果表明，ZnO成功修饰在GO表面。ZnO-GO陶瓷涂层均匀致密，平均厚度为150 μm，显微硬度为163.5~233.1 HV。在载荷为10 N、往复频率为1 Hz，持续时间为30 min的摩擦条件下，ZnO-GO复合涂层与氮化硅小球对磨的摩擦系数为0.62~0.52，磨损率为3.819×10–4~0.943×10–4 mm3/(N.m)。随着含量的增加，摩擦系数下降，磨损率也减少。结论 氧化锌-氧化石墨烯杂化材料的添加可显著提升陶瓷涂层的显微硬度，并降低涂层的磨损率。 |

| By preparing zinc oxide-graphene oxide (ZnO-GO) hybrid and implanting it into the ceramic coating, the bonding strength between the graphene oxide and the coating interface is improved, thereby improving the microhardness and wear resistance of the coating. ZnO-GO hybrid was prepared by a simple hydrothermal method, and analyzed the nanometers by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, and scanning electron microscopy (SEM). The hybrid materials were characterized. In addition, prepared phosphate ceramic coatings (CBPCs) with different content of ZnO-GO hybrid materials on stainless steel by sol-gel method. The wear behavior of the ceramic coating was studied through the wear test, and the wear morphology of the coating was observed to discuss the wear mechanism of the ZnO-GO coating. X-ray diffraction (XRD), Fourier infrared spectroscopy (FTIR), Raman spectroscopy (Raman) and scanning electron microscope (SEM) analysis results show that ZnO was successfully modified on the GO surface. The ZnO-GO ceramic coating is uniform and dense, with an average thickness of 150 μm and a microhardness of 163.5~233.1 HV. Under the friction condition of 10 N load, reciprocating frequency 1 Hz and duration 30 min, the friction coefficient of the ZnO-GO composite coating and the silicon nitride ball to the grinding is 0.62~0.52, and the wear rate is 3.819×10–4~0.943×10–4 mm3/(N.m). As the content increases, the friction coefficient decreases and the wear rate also decreases. Results indicate the addition of zinc oxide- graphene oxide hybrid can significantly improve the microhardness of the ceramic coating and reduce the wear rate of the coating. |
