| 摘要 | Rare earth has been widely used in materials manufacturing to improve mechanical properties. In this paper, Nano-CeO2-modified WC/12Co coating with biomodal-sized WC was produced by using high speed oxygen flaming (HVOF) spraying technology. XRD phase analysis showed that the decarburization of WC in coating doped with nano-CeO2 was slighter than no-doped coating. Potentiodynamic polarization showed that the nano rare earth modifier had improved the corrosion resistance of WC/12Co coating. In addition, long-term immersion in 3.5 wt.% NaCl solution was conducted and the surface morphologies after immersed 200 h were observed to investigate the corrosion mechanisms. The results showed WC-12Co coatings with 2 wt.% nano-CeO2 possessed better corrosion resistance and the one without nano rare earth was corroded seriously. The positive effect of CeO2 on corrosion resistance of WC/12Co coating can be attributed to the improvement of interfacial strength between Co binder phase and WC particles. |
