| Abstract: | FeCrBSiMnNbY amorphous/nanocrystalline coatings were fabricated by high velocity arc spraying processing. The microstructure of the coating was characterized by SEM, TEM and XRD. The formation mechanism of amorphous/nanocrystalline was discussed. The elevated temperature erosion behavior of the coating was also investigated. The results show that the microstructure of the coating consists of amorphous phase and α (Fe,Cr) nanocrystalline. The coating is dense and homogeneous with low porosity of 1.7%. The coating has excellent elevated temperature erosion resistance. With the impingement angles increasing, the erosion rate of the coating increases. With the erosion temperature increasing, the erosion resistance increases, too. |
| Keywords: | FeCrBSiMnNbY system amorphous nanocrystalline coating |
