Nickel-based monocrystalline superalloy with improved oxidation resistance and method of production |
| 摘要 |
A nickel-based monocrystalline superalloy suitable for turbine engine blades is obtained by adding to the alloy at least one element chosen from erbium and silicon, at a concentration by weight of 50 to 500 ppm for Er and of 500 to 1000 ppm for Si and, optionally, hafnium at a concentration by weight of 500 to 1000 ppm.
