MASKING METHOD FOR PRODUCING A COMBINATION OF BLADE TIP HARDFACING AND EROSION-PROTECTION COATING |
| 摘要 |
A method for manufacturing a blade (1) for a turbomachine, the blade having a hardfacing on its tip (4) and an erosion-protection coating (13) at least on its airfoil (3) is provided. Initially, a blade tip hardfacing is applied to the blade tip and, subsequently, a mask (10) is positioned in the region of the blade tip hardfacing, the mask covering the blade tip hardfacing, and, subsequently, the erosion-protection coating is deposited. The mask is removed after the erosion-protection coating is completed. A blade for a turbomachine, the blade having a hardfacing on its tip (4) and an erosion-protection coating (13) at least on its airfoil (3) is also provided. The erosion-protection coating at least partially covers the blade tip hardfacing, and the thickness of the erosion-protection coating decreases continuously in and/or toward the region of the blade tip hardfacing. |

1. A method for manufacturing a blade for a turbomachine, the blade having a tip and an airfoil, the blade having hardfacing on the tip and an erosion-protection coating at least on the airfoil, the method comprising;
applying initially a blade tip hardfacing to the blade tip; and positioning subsequently a mask in the region of the blade tip hardfacing, the mask covering the blade tip hardfacing; depositing subsequently the erosion-protection coating; and removing the mask after the erosion-protection coating is deposited. |
