| Abstract: |
| Fe-Al/Cr3C2composite coating which spraying materials were researched by us was made on the 20 steel by High Velocity Flame Spraying(HVFS). High-temperature corrosion resistance property of HVFS Fe-Al/Cr3C2 coating at 650℃ was researched. High-temperature corrosion resistance mechanism was analyzed by SEM, EDS and XRD. The results show that the high-temperature corrosion resistance property of Fe-Al/Cr3C2is better than 20 steel obviously and Fe-Al coating at 650 ℃ , the shape of the corrosion curve is parabola, the inner corrosion coating are densely Al2O3and Cr2O3which protect coatings from being corrosion.Fe-Al/Cr3C2composite coating has widely application foreground through field use. |
