NICKEL OR COBALT BASE SUPERALLOY ARTICLE HAVING AN ALUMINIDECOATING THEREON AND PROCESS OF MANUFACTURE |
| 摘要 |
<p>A protective coating system for superalloys is described. The coating is an yttrium enriched aluminide, and can be formed by aluminizing an MCrAlY or overlay coated superalloy, wherein during the aluminizing process, aluminum diffuses completely through the MCrAlY coating and into the substrate. The coating system exhibits desirable oxidation resistance and resistance to thermal fatigue cracking.</p> |
