Abstract
Official abstract text for this publication.
A process for applying a chromium layer on a substrate, specifically a turbine engine airfoil, by contacting at least a portion of the substrate with a gaseous chromium wherein the gaseous chromium is generated from a substantially nitrogen free source.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coated substrate, comprising: a substrate having a surface; and a chromium layer deposited directly on the surface, and substantially free of nitrides on the chromium layer, wherein the substrate has internal passageways, and the coating is on the internal passageways. 2. The coated substrate of claim 1 , wherein the substrate is an aircraft engine airfoil. 3. The coated substrate of claim 1 , wherein the substrate is a low pressure turbine stage airfoil. 4. The coated substrate according to claim 1 , wherein the chromium layer has a thickness of between 0.3 and 1.3 mils. 5. The coated substrate according to claim 1 , wherein the substrate is made of a nickel-based superalloy. 6. A coated substrate, comprising: a substrate having a surface, and a chromium layer deposited directly on the surface, and substantially free of nitrides on the chromium layer, wherein the substrate has internal passageways, and the coating is on the internal passageways, wherein the coated substrate is produced by: contacting at least a portion of the substrate with a vapor comprising a gaseous chromium wherein the gaseous chromium is generated from a mixture comprising a chromium source and a substantially nitrogen free activator. 7. The coated substrate according to claim 6 , wherein the chromium layer has a thickness of between 0.3 and 1.3 mils.
