Rough dense ceramic sealing surface in turbomachines |
| 摘要 |
<p>An abrasive coating (60) is formed on a rotor shaft (50) that rotates with respect to cantilevered vanes (26). The coating is formed by thermal spray techniques and comprises a ceramic layer (64) on a metal bond coat (62). The coating surface is roughened by crush grinding or by grit blasting to increase the abradability of the surface.</p> |
