Anti-diffusion barrier material used for profile elements and other gas turbine motor components contains chromium together with tungsten or rhenium or ruthenium or combinations of these elements to prevent aluminum migration |
摘要 |
Anti-diffusion barrier layer material incorporates: (a) 15 to 95 % by atoms of chromium; and (b) 5 to 60 % by atoms of an element chosen from the assembly made up of rhenium, tungsten and ruthenium or a combination of these elements. The layer produced by this material is arranged between a substrate and an aluminum rich coating to prevent the migration of aluminum from the coating into the substrate. Independent claims are also included for the following: (a) a component for use in a high temperature oxidizing atmosphere incorporating an anti-diffusion barrier made of this material; (b) a method for preventing aluminum migration from an aluminum rich coating to a substrate. |
