| Abstract: |
| 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. |
